Migrating from HubSpot to GoHighLevel (GHL) is a data-architecture translation problem, not a CSV upload. HubSpot uses a deeply relational schema — Companies contain Contacts, Contacts link to Deals via an explicit Associations API, and Activities fan out across every object. GoHighLevel is contact-centric: everything radiates from a flat Contact record, Opportunities live inside Pipelines, and Companies exist as a loosely coupled grouping object.
A CSV export from HubSpot flattens those multi-object relationships, silently duplicates company data across contact rows, and leaves you with zero automation logic on the other side. Understanding the structural mismatch before you export a single record is what separates a clean migration from weeks of manual cleanup.
This guide covers the object-mapping decisions you need to make, the API constraints on both sides, every viable migration method and its trade-offs, and the edge cases that break most DIY attempts. If you're migrating from a different CRM to GoHighLevel, see our Salesforce to GoHighLevel migration guide or Close to GoHighLevel migration guide for comparisons against GHL's data model.
Why Companies Migrate from HubSpot to GoHighLevel
The drivers are almost always a combination of three things:
- Cost consolidation. HubSpot's per-seat, per-Hub pricing adds up fast. GoHighLevel bundles CRM, pipeline management, funnels, SMS/email, appointment scheduling, and reputation management into a single subscription — typically $297–$497/month with unlimited sub-accounts.
- Agency model fit. GoHighLevel was built for agencies. Its sub-account architecture lets you spin up isolated client environments, white-label the entire platform, and resell it as your own SaaS product. HubSpot's partner model doesn't offer this.
- Operational simplicity. HubSpot's power comes from configurability — Workflows, custom objects, multi-tier permission sets, Operations Hub custom code. Teams running fewer than ~50 users who primarily need lead capture, pipeline management, and marketing automation often find GHL covers 80% of those use cases with less admin overhead.
The architectural difference matters more than the subscription difference.
HubSpot vs. GoHighLevel: Architectural Differences That Break Migrations
HubSpot's model is a relational CRM. Standard objects — Companies, Contacts, Deals, Tickets, Products — are connected by an explicit Associations API with labeled relationship types. HubSpot supports Custom Objects on Enterprise-tier subscriptions, with flexible schema definitions and many-to-many association types. Activities (calls, emails, meetings, notes, tasks) are linked as Engagements across multiple objects simultaneously. HubSpot also lets portals rename objects — your source may call the Company object an "Account." (developers.hubspot.com)
GoHighLevel's model is contact-centric. The standard entities are Contacts, Companies, Opportunities (inside Pipelines), and as of October 2025, Custom Objects. The critical differences:
| Dimension | HubSpot | GoHighLevel |
|---|---|---|
| Core unit | Object-relational (any-to-any associations) | Contact-centric (everything radiates from Contact) |
| Deals/Opportunities | Deals exist independently, link to multiple Contacts and Companies | Opportunities must be linked to a valid Contact ID |
| Custom Objects | Unlimited definitions on Enterprise | Up to 10 per sub-account (all plans) |
| Activities | First-class Engagements API, linked across objects | Notes, Tasks — no unified engagement model |
| Automations | Workflows with if/then branching, custom code actions | Workflows with triggers, actions, conditions |
| Multi-contact deals | Native — a Deal can associate with N Contacts | Requires duplicate opportunities toggle |
Key constraint: Each GoHighLevel opportunity must be linked to a Contact. You cannot import opportunities without associated contact data. If your HubSpot deals have multi-contact associations, you need to decide which contact becomes the primary owner on the GHL side.
If your HubSpot design depends on multi-object associations, association labels, or custom objects that drive automation, reporting, or service workflows, expect translation work rather than direct portability.
Migration Approaches: CSV vs. API vs. Middleware vs. Managed Service
Native CSV Export/Import
How it works: Export Contacts, Companies, and Deals from HubSpot as CSV files (Settings → Export), then import them into GoHighLevel via Contacts → Import Contacts or Opportunities → Import. (knowledge.hubspot.com)
When to use it: Under ~2,000 contacts with flat data — no custom objects, no complex deal-contact associations, minimal activity history.
Pros:
- Zero engineering effort
- Free
- Fast for small datasets
- Good for pilot loads and data cleanup rehearsals
Cons:
- Relationships are destroyed. A CSV export flattens multi-object associations. Company → Contact → Deal linkages become disconnected rows.
- Activities don't export via CSV. Notes, call logs, emails, meetings — none come through HubSpot's standard CSV export. You need the Engagements API for those.
- Custom object data requires separate exports and cannot be re-associated via CSV import on the GHL side.
- GHL's CSV import has a 30MB file size limit per upload. Large datasets must be split. (help.gohighlevel.com)
- Companies are not part of the same import flow as contacts in GHL. (help.gohighlevel.com)
Complexity: Low | Risk: High for anything beyond basic contact lists
For a deeper analysis of CSV limitations, see Using CSVs for SaaS Data Migrations: Pros and Cons.
API-Based Migration (HubSpot APIs → GoHighLevel APIs)
How it works: Write extraction scripts against HubSpot's CRM API (REST, v3) to pull Contacts, Companies, Deals, Engagements, and Custom Objects. Transform the data to match GHL's schema, then push it via GHL's V2 API.
When to use it: 5,000+ records, multi-object relationships, activity history preservation, custom objects.
Pros:
- Full control over field mapping and data transformation
- Preserves relationships by creating records in dependency order (Companies → Contacts → Opportunities) and re-linking via IDs
- Can migrate activities (notes, tasks) that CSV cannot
- Supports delta sync before cutover
Cons:
- Requires engineering time (typically 40–80+ hours for a complex migration)
- Must handle rate limits on both sides (see API Rate Limits section)
- Error handling, retry logic, and idempotency must be built from scratch
- GHL's V2 API has evolving endpoints — the legacy GET /contacts endpoint is deprecated; use Search Contacts instead
- Older HubSpot custom-object scripts may break because undocumented base-name object paths were removed on June 24, 2025. Use
objectTypeIdor supported custom-object identifiers instead. (developers.hubspot.com)
Complexity: High | Risk: Medium (if properly engineered)
Middleware / Integration Platforms (Make, Zapier)
How it works: Use a no-code platform like Make or Zapier to connect HubSpot triggers to GoHighLevel actions. Typically used for ongoing sync rather than bulk migration.
When to use it: Ongoing data sync between the two platforms during a phased migration, or for small-scale one-time transfers (<1,000 records).
Pros:
- No custom code
- Visual flow builder
- Supports OAuth 2.0 for both platforms
- Good for event-driven updates post-cutover
Cons:
- Not designed for bulk migration. Zapier processes records one at a time. Make handles batches but is still constrained by execution limits and API rate limits.
- At scale, you'll hit both HubSpot's burst limit and GHL's 100 requests/10 seconds limit before finishing a meaningful dataset.
- No native support for re-linking associations or preserving multi-level relationships
- Ongoing platform cost adds up ($100–$300+/month for high-volume scenarios)
- Connector drift is real: Make already flags some HubSpot modules as deprecated. Build your historical move on stable APIs, not connector convenience. (make.com)
Complexity: Medium | Risk: High for bulk migrations; acceptable for ongoing sync
Custom ETL Pipeline
How it works: Land HubSpot data in a staging database (PostgreSQL, MongoDB). Store normalized records plus raw payloads. Build deterministic transforms and crosswalk tables. Write batches to GHL with checkpoints, retries, and dead-letter handling. Re-run deltas until cutover.
When to use it: Enterprise scale, compliance-sensitive moves, multi-wave migrations, or zero-downtime requirements.
Pros:
- Best auditability and resumability
- Raw source payloads preserved for rollback analysis
- Supports large datasets and phased migration
Cons:
- Highest build cost
- Easy to underestimate QA time
- Needs ownership after the first successful run
Complexity: High | Risk: Medium-High (most in-house ETLs fail on the non-happy paths: duplicate logic, orphaned associations, partial retries, and cutover deltas)
For more on that failure pattern, read The Data Migration Risk Model: Why DIY AI Scripts Fail.
Managed Migration Service
How it works: A migration partner handles extraction, transformation, loading, relationship rebuilding, validation, and rollback planning.
When to use it: Enterprise datasets (50K+ records), complex custom objects, multi-pipeline configurations, or teams that cannot dedicate engineering resources for 2–4 weeks.
Pros:
- Handles API rate limiting, pagination, retry logic, and deduplication
- Preserves relationships across all object types
- Validation and QA built into the process
- Zero downtime — sales teams keep working in HubSpot during migration
Cons:
- External cost
- Requires trust in the partner's security posture
Complexity: Low (for your team) | Risk: Low
Comparison Table
| Method | Best For | Relationships Preserved | Activities Migrated | Complexity | Risk |
|---|---|---|---|---|---|
| CSV Export/Import | <2K contacts, flat data | ❌ No | ❌ No | Low | High |
| API-Based (Custom) | 5K+ records, engineering team available | ✅ Yes | ✅ Yes | High | Medium |
| Middleware (Make/Zapier) | Ongoing sync, small batches | ⚠️ Partial | ⚠️ Limited | Medium | High (at scale) |
| Custom ETL Pipeline | Enterprise, zero-downtime | ✅ Yes | ✅ Yes | High | Medium-High |
| Managed Service | Enterprise, complex schemas | ✅ Yes | ✅ Yes | Low | Low |
Recommendations by Scenario
- Small business, <2K contacts, no custom objects: CSV export is adequate. Accept that you'll lose associations and rebuild pipelines manually.
- Mid-market, 5K–50K records, some custom fields: API-based migration works if you have a developer who can commit 2–3 weeks. Otherwise, use a managed service.
- Enterprise, 50K+ records, custom objects, multi-pipeline: Managed migration service. The engineering cost of building, testing, and debugging a custom ETL pipeline almost always exceeds the cost of a specialist.
- Ongoing sync during phased rollout: Middleware (Make) for contact-level sync, combined with API scripts for the initial bulk load.
- No team to own retries, validation, and rollback: Buy the execution instead of building it.
Data Mapping: Translating HubSpot Objects to GoHighLevel
Every mapping decision you make here determines the shape of your GHL CRM for years. This is architecture work, not a spreadsheet exercise.
Object-Level Mapping
| HubSpot Object | GoHighLevel Equivalent | Notes |
|---|---|---|
| Companies (or renamed "Accounts") | Companies | 1:1 mapping. GHL Companies are loosely coupled to Contacts. Contacts and Companies import separately. |
| Contacts | Contacts | Direct mapping. GHL's core entity. |
| Deals | Opportunities (in Pipelines) | Must be linked to a Contact. Create pipelines/stages first, then import. |
| Tickets | Opportunities (separate pipeline) or Custom Object | GHL has no native Tickets object. Use a dedicated "Support" pipeline or a Custom Object. |
| Custom Objects | Custom Objects (max 10) | Map highest-priority objects first. If HubSpot has >10, consolidate or drop. |
| Engagements (Notes) | Notes | Can be migrated via API. Loses cross-object linking. |
| Engagements (Tasks) | Tasks | Basic mapping. No multi-object association in GHL. |
| Engagements (Emails, Calls, Meetings) | Notes (as text records) | GHL has no equivalent engagement type. Flatten to notes or accept data loss. |
| Products | Products (under Payments) | Manual recreation or API. |
| Workflows | Workflows (manual rebuild) | Cannot be exported from HubSpot. Must be rebuilt from scratch. |
| Association labels | Crosswalk table + custom metadata | Preserve in staging even if GHL cannot use them everywhere. Easy to lose during CSV-only migrations. |
Field-Level Mapping
| HubSpot Field | HubSpot Type | GoHighLevel Field | GHL Type | Transformation |
|---|---|---|---|---|
hs_object_id |
Text | Custom Field (hubspot_id) |
Text | Keep for crosswalks and audit |
firstname |
Text | firstName |
Text | Direct |
lastname |
Text | lastName |
Text | Direct |
email |
Text | email |
Text | Lowercase, validate duplicates |
phone |
Text | phone |
Text | Normalize to E.164 format |
company |
Text | companyName |
Text | Direct (or link to Company object) |
lifecyclestage |
Enumeration | Tag or Custom Field | Text/Dropdown | Map internal values — not display labels |
dealstage |
Enumeration | Pipeline Stage | Stage ID | Map to pre-created pipeline stages |
dealname |
Text | name (Opportunity) |
Text | Direct |
amount |
Number | monetaryValue |
Number | Normalize currency/precision |
closedate |
Date | Custom Field | Date | Convert epoch timestamps to ISO 8601 |
hubspot_owner_id |
Lookup | assignedTo |
User ID | Map HubSpot owner IDs → GHL user IDs |
hs_lead_status |
Enumeration | Tag or Custom Field | Dropdown | Map picklist values |
| Custom properties | Various | Custom Fields | Various | Create custom fields in GHL first |
Picklist mapping matters. HubSpot enumeration fields use internal values (e.g., appointmentscheduled) that differ from display labels ("Appointment Scheduled"). Always map against internal values, not labels, to avoid silent mismatches. HubSpot properties are API-addressable by internal names, and GHL requires destination fields to exist before imports can map to them. (developers.hubspot.com)
Handling Custom Objects
GoHighLevel now supports custom objects on all plans, with a hard cap of 10 custom objects per sub-account. Each custom object supports its own custom fields and can be linked to Contacts, Companies, Opportunities, and other Custom Objects with 1:1, 1:Many, and Many:Many relationship types.
The catch is feature coverage: Custom Objects are not yet supported in Email Campaigns, bulk email/SMS, Conversations, Funnels/Websites, Calendars, Reputation/Reviews, Payments/Invoicing, or Company views. If a HubSpot custom object drives one of those processes, flatten it into standard fields, tags, opportunities, or notes instead of forcing a 1:1 port. (help.gohighlevel.com)
Older guides that say GoHighLevel has no custom objects are outdated. The current limitation is not object existence — it's uneven feature coverage across GHL's product surface.
If your HubSpot instance has more than 10 custom object definitions:
- Prioritize — Rank custom objects by business criticality
- Consolidate — Merge related objects into a single GHL custom object with a "type" dropdown field
- Flatten — Move low-priority custom object data into custom fields on the Contact or Opportunity record
- Drop — Accept that some rarely-used objects won't migrate
The GHL REST API supports CRUD operations on custom objects and their records, so API-based migration is possible — but you must create the schema (object definitions, fields, associations) in GHL before importing records.
API Rate Limits: The Bottleneck You Must Plan For
Rate limits are the single biggest engineering constraint in any HubSpot ↔ GoHighLevel migration. Ignoring them doesn't cause graceful degradation — it causes 429 errors, dropped records, and corrupted partial imports.
HubSpot Extraction Limits
HubSpot's rate limits depend on your subscription tier and app type: (developers.hubspot.com)
| App Type / Tier | Burst Limit | Daily Limit |
|---|---|---|
| Private app — Free/Starter | 100 requests / 10 sec | 250,000 / day |
| Private app — Professional | 190 requests / 10 sec | 650,000 / day |
| Private app — Enterprise | 190 requests / 10 sec | 1,000,000 / day |
| Public (OAuth) marketplace app | 110 requests / 10 sec | Per-account |
| CRM Search API (all tiers) | 5 requests / sec | Shared across all search endpoints |
Key details:
- Batch endpoints count as one request. HubSpot's batch create/update endpoints process up to 100 records per call. Use them aggressively during extraction. This is the single most effective way to stay under burst limits.
- The CRM Search API is your real bottleneck. At 5 requests/second shared across all object searches (contacts, deals, companies), deduplication checks during import become painfully slow. The Search API returns up to 200 records per response.
- 429 errors require exponential backoff with jitter. Don't use fixed
sleep()intervals. Implement a token-bucket rate limiter and honor theRetry-Afterheader. - The Exports API is an alternative for initial snapshots. It can include up to four associated object types per export, defaults to 1,000 associated records per row unless overridden, and splits large exports into multiple files once they exceed 1,000,000 rows. Limit: one export at a time, 30 exports per rolling 24 hours. (developers.hubspot.com)
GoHighLevel Loading Limits
GoHighLevel's V2 API enforces: (marketplace.gohighlevel.com)
| Limit Type | Value |
|---|---|
| Burst limit | 100 requests / 10 seconds per app per Location |
| Daily limit | 200,000 requests / day per app per Location |
| Contacts per response | Max 100 (default 20) |
| Pagination | Cursor-based via startAfterId and startAfter |
Key details:
- V1 API reached end-of-support on December 31, 2025. All new integration work must target V2. Do not start a new project on legacy V1 API keys. (marketplace.gohighlevel.com)
- The GET /contacts endpoint is deprecated. Use the Search Contacts endpoint instead.
- Pagination is cursor-based, not offset-based. You must pass
startAfterIdandstartAfterfrom the previous response to fetch the next page. You cannot parallelize page fetches — each request depends on the previous response. - 200K daily requests sounds generous until you do the math. Creating 50K contacts + 50K opportunities + 30K notes + association calls = easily 150K+ API calls for a mid-sized migration. Add validation reads and you're at the ceiling.
Authentication choice matters. For single-account migrations, use a Private Integration Token — simpler setup, no OAuth flow. For multi-location agency migrations, use OAuth 2.0 with proper token refresh handling.
The Workflow Trap: Why Automations Don't Migrate
This is the single most underestimated cost in any HubSpot-to-GHL migration.
HubSpot workflows, sequences, conditional logic, and automation rules cannot be exported via API or CSV. The only export options HubSpot provides are a metadata spreadsheet and a PNG screenshot of the workflow — both of which omit performance data, workflow history, and email content used inside workflows. There is no JSON export, no portable format, and no import mechanism in GoHighLevel for HubSpot workflow definitions. (knowledge.hubspot.com)
What this means in practice:
- Every workflow must be manually documented in HubSpot (triggers, conditions, branches, actions, delays)
- Every workflow must be manually rebuilt in GoHighLevel's workflow builder
- Trigger logic is different. HubSpot uses enrollment triggers with re-enrollment rules; GHL uses event-based triggers with action sequences
- Branching logic differs. HubSpot's if/then branches with multiple conditions must be restructured into GHL's condition nodes
- Custom code actions don't transfer. If you're running Node.js or Python in HubSpot Operations Hub custom code actions, that logic must be rewritten — potentially as GHL webhook actions calling external endpoints
Budget 40–60% of total migration time for workflow rebuilding. On a typical 10-pipeline HubSpot instance with 30+ workflows, manual workflow recreation often takes longer than the data migration itself. Audit and prioritize — not every HubSpot workflow needs to be recreated in GHL.

Step-by-Step API Migration Architecture
Here's the ETL architecture that works for HubSpot → GoHighLevel API migrations.
Phase 1: Extract from HubSpot
import requests
import time
HUBSPOT_TOKEN = "pat-na1-xxxxx"
BASE_URL = "https://api.hubapi.com"
HEADERS = {"Authorization": f"Bearer {HUBSPOT_TOKEN}"}
def extract_contacts(properties=["firstname", "lastname", "email", "phone", "company"]):
"""Extract all contacts using HubSpot CRM API v3 with pagination."""
contacts = []
url = f"{BASE_URL}/crm/v3/objects/contacts"
params = {"limit": 100, "properties": ",".join(properties)}
after = None
while True:
if after:
params["after"] = after
response = requests.get(url, headers=HEADERS, params=params)
if response.status_code == 429:
retry_after = int(response.headers.get("Retry-After", 10))
time.sleep(retry_after)
continue
data = response.json()
contacts.extend(data.get("results", []))
paging = data.get("paging", {})
after = paging.get("next", {}).get("after")
if not after:
break
time.sleep(0.1) # Respect burst limits
return contactsFor associations, extract them explicitly — don't assume the object export tells the full relational story:
# HubSpot Associations v4 batch read
POST /crm/v4/associations/contacts/companies/batch/read
POST /crm/v4/associations/contacts/deals/batch/readPhase 2: Transform
def transform_contact(hs_contact, owner_map, tag_map):
"""Transform HubSpot contact to GoHighLevel contact schema."""
props = hs_contact.get("properties", {})
ghl_contact = {
"firstName": props.get("firstname", ""),
"lastName": props.get("lastname", ""),
"email": props.get("email", ""),
"phone": normalize_phone(props.get("phone", "")),
"companyName": props.get("company", ""),
"tags": tag_map.get(props.get("lifecyclestage", ""), []),

# Map HubSpot owner to GHL user
hs_owner = props.get("hubspot_owner_id")
if hs_owner and hs_owner in owner_map:
ghl_contact["assignedTo"] = owner_map[hs_owner]
# Map custom properties to GHL custom field IDs
for hs_field, ghl_field_id in CUSTOM_FIELD_MAP.items():
if props.get(hs_field):
ghl_contact["customFields"].append({
"id": ghl_field_id,
"field_value": props[hs_field]
})
return ghl_contactPhase 3: Load into GoHighLevel

)
if response.status_code == 429:
time.sleep(10) # Back off on rate limit
return load_contact(ghl_contact) # Retry
if response.status_code in [200, 201]:
return response.json().get("contact", {}).get("id")
return NonePhase 4: Rebuild Relationships
The critical load order:
- Create Companies in GHL → store
{hubspot_company_id: ghl_company_id}mapping - Create Contacts → store
{hubspot_contact_id: ghl_contact_id}mapping - Link Contacts to Companies using GHL's company association
- Create Pipeline stages (must exist before opportunity import)
- Create Opportunities → link to Contact IDs from step 2, assign to correct pipeline/stage
- Create Custom Object records → associate with Contacts/Opportunities
- Create Notes/Tasks → attach to Contact IDs
If you skip the ID mapping steps, you'll have orphaned records with no way to reassociate them without a second pass.
Error Handling Pattern
import random
def api_call_with_retry(func, max_retries=5):
"""Exponential backoff with jitter for API calls."""
for attempt in range(max_retries):
try:
result = func()
if hasattr(result, 'status_code') and result.status_code == 429:
wait = (2 ** attempt) + random.uniform(0, 1)
time.sleep(wait)
continue
return result
except Exception as e:
if attempt == max_retries - 1:
raise
wait = (2 ** attempt) + random.uniform(0, 1)
time.sleep(wait)
return NoneEdge Cases and Failure Modes
Duplicate contacts. HubSpot deduplicates on email address. GHL's Upsert Contact API follows the location's Allow Duplicate Contact configuration. If email and phone match different existing contacts, the API updates the contact that matches the first field in the configured priority sequence and ignores the second. If your HubSpot data has contacts with no email (phone-only), you'll get duplicate-looking records. Add a deduplication check by phone number before import. (marketplace.gohighlevel.com)
Multi-contact deals. HubSpot Deals can associate with multiple Contacts. GHL Opportunities link to one primary Contact. You must decide: pick the primary contact, or create duplicate opportunities (enabled via GHL's Business Profile settings). Either way, you lose the multi-contact association.
Lifecycle stages vs. tags. HubSpot's lifecycle stage is a single-select enumeration field (Subscriber → Lead → MQL → SQL → Opportunity → Customer → Evangelist). GHL doesn't have an equivalent concept. The standard approach is to map lifecycle stages to tags, but tags lack the ordered progression logic. If your workflows depend on lifecycle stage transitions, those triggers must be rebuilt differently.
Business Name company creation. GHL has a Company Object Automation that creates and associates company records from contact imports based on the business name field. This is convenient but dangerous if source data is dirty — misspellings or spacing inconsistencies create wrong companies and bad associations. (help.gohighlevel.com)
Attachments. HubSpot stores file attachments on Engagements with their own File Manager. GHL has no equivalent file-per-engagement storage. You can store attachment URLs in custom fields or notes, but the files themselves need to be hosted elsewhere (S3, GHL's media library, etc.).
Association-heavy HubSpot records. HubSpot's Exports API defaults to 1,000 associated records per row unless you override that limit. Records with more associations will silently truncate. (developers.hubspot.com)
HubSpot custom object breaking change. Undocumented base-name object paths for custom objects were removed on June 24, 2025. If you're running older extraction scripts, they may break. Use objectTypeId or supported custom-object identifiers instead. (developers.hubspot.com)
Custom object feature gaps in GHL. Even though custom objects exist in GHL, they don't surface in Email Campaigns, Conversations, Calendars, or Payments views. If your HubSpot custom object drives any of those processes, you'll need a different target structure.
Pre-Migration Planning Checklist
Before writing a single line of migration code:
- Audit HubSpot data: Count records per object (Contacts, Companies, Deals, Tickets, Custom Objects, Engagements). Remove unused/test data.
- Document all active workflows: Note triggers, conditions, branches, and actions. Prioritize which ones to rebuild in GHL.
- Map owners: Export HubSpot user list; create matching users in GHL. Build the owner ID mapping table.
- Define custom fields in GHL first. Create all custom fields (Contact-level and Opportunity-level) before importing data. You need GHL custom field IDs for API-based imports.
- Create pipelines and stages in GHL first. Opportunity imports reference pipeline and stage names — they must already exist.
- Define scope: What is operationally required on day one? What can remain archived in HubSpot? Which objects need historical fidelity versus summary notes?
- Choose a migration strategy:
- Big bang: All data moves at once, single cutover date. Simpler but riskier.
- Phased: Move contacts first, then deals, then activities. Allows validation between phases.
- Incremental: Sync new records via middleware while bulk-loading historical data via API. Usually the best approach for serious moves because it gives you room to validate while users keep working.
- Back up everything. Full HubSpot export before starting. Store it separately from both platforms. This is your rollback.
Validation and Testing
A migration without validation is just data loss you haven't discovered yet.
Record count comparison: After each phase, compare source counts (HubSpot) vs. destination counts (GHL). Contacts, Companies, Opportunities — every object type should match within a tolerance of <1% (accounting for deduplication).
Field-level validation: Pull a random sample of 50–100 records. Manually verify that custom fields, tags, pipeline stages, and monetary values transferred correctly. Pay special attention to:
- Date fields (timezone shifts can silently change dates)
- Phone numbers (formatting normalization)
- Dropdown/picklist values (internal value vs. display label mismatches)
- Owner assignments
Relationship validation: For sampled records, verify that:
- Contacts are linked to the correct Companies
- Opportunities are in the correct pipeline and stage
- Opportunities are linked to the correct Contacts
- Custom objects are associated to the right parent records
UAT process: Have 2–3 sales reps use GHL for 48–72 hours with real data before full team cutover. They'll find issues automated testing can't catch — missing fields they rely on, pipeline views that don't match their workflow, notes that didn't carry over.
Delta replay test: Before final cutover, replay any records created or modified during the migration window and verify they land correctly.
Rollback plan: Keep HubSpot active for a minimum of 30 days post-migration cutover. Don't cancel the subscription until your team has validated all critical functions in GHL. A practical rollback plan is usually a roll-forward plan: keep HubSpot as the source of truth until UAT signoff, replay deltas into GHL, then switch operational ownership once validation passes.
Post-Migration Tasks
Rebuild workflows. Start with highest-impact automations — lead assignment, booking reminders, pipeline stage change notifications — and work down. Separate transport work from process redesign. That keeps migration bugs from being confused with implementation bugs.
Rebuild reporting. HubSpot dashboards and reports don't migrate. Recreate key reports in GHL's reporting module or connect to an external BI tool.
Train the team. GHL's interface is different enough from HubSpot that even experienced CRM users need onboarding. Focus on: where contacts live, how pipelines work, how to create/view opportunities, and how the workflow builder differs.
Monitor for 30 days. Watch for:
- Duplicate contact creation from ongoing lead sources
- Workflow misfires (wrong triggers, missing conditions)
- Data inconsistencies surfaced by sales reps
- API integration failures if you're running ongoing sync
- Orphaned opportunities and bad owner assignments
Archive source data. Keep raw HubSpot exports and API payloads so you can answer audit questions later.
Best Practices That Reduce Risk
- Back up before anything. Full HubSpot export, stored separately from both platforms.
- Run a test migration first. Import 100–200 records into a sandbox or disposable GHL sub-account. Validate thoroughly before scaling up.
- Create the GHL schema before importing data. Custom fields, pipelines, stages, custom objects — all must exist before the first API call.
- Carry source IDs forward. Keep original HubSpot record IDs as custom fields. These are your crosswalk keys and your audit trail.
- Migrate in dependency order. Companies → Contacts → Opportunities → Custom Objects → Activities.
- Implement idempotency. If your script fails mid-migration, you need to restart without creating duplicates. Tag migrated records or maintain an ID mapping database.
- Don't replicate HubSpot in GHL. The platforms have different architectures for good reasons. Adapt your processes to GHL's model rather than forcing HubSpot's relational structure into a contact-centric system.
- Freeze schema changes near cutover. New fields mid-run create mapping drift.
- Be selective with history. Migrate what operators will actually use, not everything because it exists.
- Document everything. Field mappings, owner mappings, workflow logic, picklist value translations — this documentation is your safety net.
When a Managed Migration Service Makes Sense
Build in-house when:
- Your dataset is small (<5K contacts) and flat
- You have a developer who can dedicate 2+ weeks exclusively to migration
- You don't need to preserve activity history
- You have one pipeline with standard fields
Use a managed service when:
- You have 10K+ records with multi-level relationships
- Custom objects are in play (especially >5)
- You need activity history (notes, tasks) preserved
- Your team cannot absorb 2–4 weeks of engineering time
- Zero downtime is a hard requirement — sales cannot stop working during migration
- You've attempted a DIY migration and hit rate limit issues, data corruption, or broken associations
The hidden cost of DIY migration isn't the initial script — it's the debugging. Rate limit handling, pagination edge cases, partial failures, deduplication conflicts, and association rebuilding consume 3–5x the time of the initial development.
ClonePartner handles the full ETL pipeline — extraction from HubSpot (including activities, custom objects, and associations), transformation with field-level mapping, and loading into GoHighLevel with proper relationship rebuilding. We manage both platforms' rate limits, handle cursor-based pagination, and run validation checks at every phase. Your sales team keeps working in HubSpot while data syncs to GoHighLevel in the background, with zero downtime.
Frequently Asked Questions
- Can I export HubSpot workflows to GoHighLevel?
- No. HubSpot workflows cannot be exported via API or CSV. The only exports available are a metadata spreadsheet and a PNG screenshot, both of which omit performance data, workflow history, and email content. All workflow logic — triggers, conditions, branches, delays, and actions — must be manually documented and rebuilt from scratch in GoHighLevel's workflow builder.
- What are GoHighLevel's API rate limits for migration?
- GoHighLevel's V2 API enforces a burst limit of 100 requests per 10 seconds and a daily limit of 200,000 requests per app per Location. Contacts are returned in pages of up to 100 records, paginated via cursor-based startAfterId parameters. The V1 API reached end-of-support on December 31, 2025.
- Does GoHighLevel support custom objects from HubSpot?
- Yes. GoHighLevel supports up to 10 custom objects per sub-account on all plans, with 1:1, 1:Many, and Many:Many relationships. However, custom objects are not yet supported in Email Campaigns, Conversations, Calendars, Funnels, or Payments — so if your HubSpot custom object drives one of those processes, you'll need to flatten it into standard fields or tags.
- How long does a HubSpot to GoHighLevel migration take?
- A small migration (under 5K contacts, flat data) can be done in 2–5 days via CSV. A complex migration with custom objects, multi-pipeline deals, and activity history typically takes 2–6 weeks via API, with 40–60% of that time spent rebuilding workflows manually.
- Will I lose data migrating from HubSpot to GoHighLevel?
- Potential data loss areas include: email, call, and meeting engagement history (GHL has no equivalent engagement type — these must be flattened to notes), multi-contact deal associations (GHL opportunities link to one primary contact), HubSpot workflow logic (must be manually rebuilt), and custom objects beyond GHL's 10-object limit. Proper planning mitigates most risks.
