Migrate from Close to Highlevel

MIGRATION OVERVIEW

Why teams migrate from Close to Highlevel

There is no native migration path between Close CRM and GoHighLevel. Close uses a Lead-centric data model where contacts, opportunities, tasks, and activities are nested under a parent Lead object, while GoHighLevel is Contact-centric with standalone Contact records, separate Company objects, and Opportunities linked to Contacts within Pipelines. Migrating between them requires flattening Close's hierarchical structure, pre-creating custom fields and pipeline stages in GHL, and using a combination of CSV imports and API-based data injection—since activity history (calls, emails, SMS) can only be exported from Close as JSON and cannot be imported into GHL via CSV.

KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Close to Highlevel migration.

Most Critical

Lead-to-Contact Model Flattening

Close nests contacts, opportunities, tasks, and activities under a parent Lead object, which must be decomposed into GHL's flat Contact + Company + Opportunity structure without duplicating or collapsing records.

Activity History Export Complexity

Close only exports activity data (calls, emails, SMS, notes) in JSON format, which GHL's native CSV importer cannot accept, requiring custom parsing, transformation, and API injection.

Opportunity Custom Field Granularity Loss

GoHighLevel stores opportunity custom fields at the contact level rather than per-opportunity, so multiple Close Opportunities under one Lead with different custom field values will overwrite each other in GHL.

CSV Import Size and Note Limits

GHL CSV imports are limited to as low as 20 MB or 10,000 rows per file, only one note per contact (max 5,000 characters), making it impossible to carry detailed activity histories through the native importer.

Close API Pagination Constraints

Close's API limits responses to 100 records per request with a hard cap of 10,000 objects via the Advanced Filtering API, requiring date-range batching and multi-pass extraction for larger datasets.

Lead Status Has No Direct Equivalent

Close treats Lead Status and Opportunity Stage as separate concepts, but GHL has no native Lead Status field, requiring it to be mapped to tags or custom fields to avoid breaking post-migration reporting.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Close to Highlevel and built proven solutions for each one.

Migration Challenge ClonePartner Status

High Complexity —

Solved

Opportunity Custom Fields

GHL saves opportunity custom field data at the contact level, so per-deal granularity is lost when a single contact has multiple opportunities with differing custom field values.

Solved

Activities (Calls, Emails, SMS)

Activity history can only be exported from Close as JSON and cannot be imported via GHL's CSV importer, requiring custom API-based injection or archival as external references.

Solved

Notes

GHL CSV import supports only one note per contact with a 5,000-character limit, meaning extensive Close activity notes, call summaries, and email logs will be silently truncated or lost.

Solved

Tasks

There is no direct CSV import path for tasks into GHL; they must be manually recreated or rebuilt using workflow triggers after migration.

Solved

Custom Engineering —

Handled

Contacts

Contacts map relatively well to GHL Contact records, but phone numbers must be normalized to E.164 format and email/phone deduplication logic must be carefully managed to prevent merge conflicts.

Handled

Companies (Leads)

Close Leads representing companies must be mapped to either GHL Company objects or Contact fields, and GHL only allows one company association per contact, complicating multi-Lead relationships.

Handled

Opportunities

Opportunities can be migrated to GHL Pipelines, but pipeline stages must be pre-created and each Close status must be explicitly mapped to a GHL stage before import.

Handled

Custom Fields

All custom fields must be manually pre-created in GHL before import and data types must be matched, as there is no automatic schema migration between the two systems.

Handled

Lead Status

Close's Lead Status has no native GHL equivalent and must be mapped to tags or custom fields, which can break reporting if conflated with Pipeline Stages.

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

Speed of automation for bulk record migration
Precision of engineers verifying integrity and business logic
Pilot migrations and sandbox testing to catch issues early
Real-time validation reports and rollback readiness

Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Close and Highlevel APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

Field mapping and transformation
Pagination, rate-limit handling, and throttling
Preserving conversation threads, attachments, and internal notes
Syncing custom fields, SLAs, and macros without breaking structure

Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

100% record-count parity between your Close data and Highlevel
Zero downtime during staged cutovers
99.9% attachment integrity (verified via checksum)
Full automation and preservation of all business rules

Our standard: Includes full SLA preservation and 48 hours of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Close or Highlevel exactly the same way—with unique automations and data. We customize every migration script to fit your exact workflow, tags, and triggers.

Our engineers adapt for:

Custom fields, ticket forms, and workflows
Multi-brand or multi-language setups
Historical imports and partial (date-based) migrations
Integration re-mapping for CRMs, chat, or feedback tools

The promise: If your data doesn't fit a standard template, we build one just for you.
