MIGRATION OVERVIEW

Why teams migrate from Monday CRM to Attio

There is no native one-click migration path from monday.com to Attio. The core challenge is a fundamental data-model mismatch: monday.com uses a flat, board-based structure with Connect Boards links (UI references, not foreign keys), while Attio enforces an object-relational schema with typed relationship attributes, lists, and workspace-wide attribute definitions. A successful migration requires custom schema restructuring—translating boards into objects, rebuilding relationship chains (Account → Contact → Deal), and re-mapping pipeline stages from board groups/Status columns into Attio's list-based stage attributes. CSV and no-code tools handle only simple flat data; preserving relationships, activity history, and pipeline context demands a custom API-based ETL pipeline.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Monday CRM to Attio migration.

Most Critical

Board-to-Object Schema Translation

monday.com's per-board column definitions must be restructured into Attio's workspace-wide object attributes with enforced types, requiring a complete schema redesign rather than a direct field copy.

Relationship Chain Reconstruction

Connect Boards columns in monday.com are UI-level references that export as text labels, not IDs, so Account → Contact → Deal relationship chains must be programmatically rebuilt as typed relationship attributes in Attio.

Activity and Email History

monday.com's Emails & Activities timeline is excluded from both board-level CSV exports and account-level data exports, so migrating communication history requires API extraction and custom transformation.

Duplicate Risk with Email Sync

If Attio's mailbox sync has already auto-created Person and Company records, any import tool without upsert capability (including Import2) will generate duplicates that must be manually resolved.

Object and Record Plan Limits

Attio enforces strict object limits per plan (e.g., 5 on Plus, 12 on Pro), so monday.com workspaces with many custom boards may require a Pro or Enterprise plan to accommodate equivalent custom objects.

Mirror and Formula Column Handling

monday.com's API returns null for Connect Boards, Dependency, and Subtasks column values in recent API versions, meaning derived and mirror column data must be recomputed or snapshot-captured before migration.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

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

Migration Challenge ClonePartner Status
High Complexity —
Solved
Deals
Deals must be migrated into Attio lists with stage attributes rather than as simple records, and pipeline stage history from monday.com's Status column groups does not have a direct import path.
Solved
Account-Contact-Deal Relationships
Connect Boards links export as plain text labels without machine-readable IDs, so the entire relationship graph must be reconstructed programmatically during the transformation phase.
Solved
Activities and Email History
The Emails & Activities timeline is excluded from all native export methods and requires API-level extraction with custom mapping to Attio's notes and communication intelligence model.
Solved
Custom Objects (Custom Boards)
Custom boards require custom objects in Attio, which are only available on Pro and Enterprise plans and count toward strict per-plan object limits.
Solved
Subitems
monday.com subitems are excluded from CSV exports and their updates are not included in board exports, requiring dedicated API queries and a custom mapping strategy to represent them in Attio.
Solved
Custom Engineering —
Handled
Contacts (People)
Contact records map to Attio's People object, but the risk increases when email sync has already created Person records in Attio, requiring deduplication or upsert logic via the API.
Handled
Custom Fields
monday.com column types (Status, Dropdown, Mirror, Formula) must be individually mapped to Attio attribute types, with Mirror and Formula columns requiring recomputation or legacy snapshots.
Handled
Pipeline Stages
monday.com models pipeline stages as board groups or Status column values, while Attio uses list-level stage attributes, requiring structural remapping and potential loss of stage transition history.
Handled
Notes
Import2 supports notes migration to Attio objects, but the CSV importer does not support notes at all, limiting options for teams using a code-free approach.
Handled
Clean Transfer
Companies (Accounts)
Account records are relatively flat and map directly to Attio's Companies object, making field-level migration straightforward with standard column-to-attribute mapping.

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:

  1. Speed of automation for bulk record migration
  2. Precision of engineers verifying integrity and business logic
  3. Pilot migrations and sandbox testing to catch issues early
  4. 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 Monday CRM and Attio 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:

  1. Field mapping and transformation
  2. Pagination, rate-limit handling, and throttling
  3. Preserving conversation threads, attachments, and internal notes
  4. 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:

  1. 100% record-count parity between your Monday CRM data and Attio
  2. Zero downtime during staged cutovers
  3. 99.9% attachment integrity (verified via checksum)
  4. 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 Monday CRM or Attio 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:

  1. Custom fields, ticket forms, and workflows
  2. Multi-brand or multi-language setups
  3. Historical imports and partial (date-based) migrations
  4. 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.

FAQ

Frequently Asked Questions

Everything you need to know about migrating from Monday CRM to Attio. Can't find what you're looking for? Talk to our team.

Can I migrate monday.com data to Attio using CSV export?
You can, but CSV exports flatten Connect Boards relationships into plain text and exclude the Emails & Activities timeline entirely. monday.com board exports are capped at 10,000 items. CSVs work for small, flat datasets under 2,000 records where relationship preservation isn't required. For anything more complex, use the API or a managed service.
What are Attio's API rate limits for migration?
Attio enforces 100 read requests per second and 25 write requests per second, per workspace. Exceeding these returns HTTP 429 with a Retry-After header. List queries also use score-based rate limits on a 10-second sliding window. At 25 writes/sec, importing 50,000 records takes at minimum ~33 minutes of pure write time.
Does Import2 work for monday.com to Attio migration?
Import2 is free and handles standard objects (Companies, People, Deals, Notes), but it cannot import into Attio Lists, cannot upsert existing records, and will create duplicates if email sync has already populated your workspace. You must delete email-sync-created records before running Import2, or use the API with assert endpoints instead.
Can I export the Emails & Activities timeline from monday.com?
Not through native exports. monday.com's account export explicitly excludes the Emails & Activities timeline. The only way to extract email history, call logs, and activity data is through monday.com's GraphQL API. This is a key reason API-based migration is recommended over CSV.
How many custom objects does Attio support?
Attio limits total objects (standard + custom) by plan: 3 on Free, 5 on Plus, 12 on Pro, and unlimited on Enterprise. Custom objects are only available on Pro and Enterprise. Companies and People count toward total object limits, so plan your monday.com board-to-object mapping accordingly.
How long does the Monday CRM to Attio migration take?
Most migrations complete within 1–5 business days, depending on data volume and complexity. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.
Will my team lose access to Monday CRM during the migration?
No. Your source system remains fully operational throughout the entire migration. We run the migration in the background with zero downtime to your current operations.
Will there be downtime when migrating from Monday CRM to Attio?
No. Our migration process is designed for zero downtime. We use a staged approach with background sync and a fast cutover, ensuring no disruption to your live business operations.
How do I validate that everything migrated correctly?
Every client receives a Migration Validation Report with comprehensive metrics including record-count parity, attachment integrity verification via checksum, and full audit logs. We also offer unlimited sample migrations so you can verify before committing.
Do I need professional help for this migration?
While simple migrations can sometimes be handled in-house, professional help ensures zero data loss, proper field mapping, and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.
Does ClonePartner provide guidance before committing?
Yes. We provide a free consultation and assessment. We'll review your data structure, discuss your requirements, and provide a detailed migration plan and fixed-price quote before you commit to anything.
