Migrate from Salesforce to Attio

MIGRATION OVERVIEW

Why teams migrate from Salesforce to Attio

There is no native one-click migration path from Salesforce to Attio. Salesforce's rigid schema—built on record types, formula fields, roll-up summaries, Apex triggers, and junction objects—has no direct structural equivalent in Attio's graph-based model of objects, relationship attributes, and lists. Every object, field, and relationship must be deliberately remapped, and computed field values (formula fields, roll-ups) must be flattened to static data or recreated using Attio workflows. Custom engineering work is required for any migration involving more than basic flat data, particularly for relationship chain preservation, activity history, and custom objects.

KEY CHALLENGES

What makes this migration complex

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

Most Critical

No Direct Schema Equivalents

Salesforce formula fields, roll-up summaries, Person Accounts, and Apex triggers have no native counterpart in Attio, requiring computed values to be flattened to static data or rebuilt with Attio workflows and AI attributes.

Relationship Chain Preservation

Salesforce's lookup and master-detail relationships (Account → Contact → Opportunity) must be remapped to Attio's relationship attributes with correct dependency ordering, or the relational context that gives CRM data its value is severed.

Record Type Consolidation

Salesforce Accounts with multiple Record Types and Page Layouts must be collapsed into single Attio Company records differentiated by list memberships and status attributes, requiring non-trivial mapping decisions.

Activity and Case Gaps

Attio's CSV importer does not support notes, and the Import2 migration path does not migrate Cases, Emails, or Meetings, leaving significant activity history at risk of being lost.

Duplicate Record Risk

Import2 creates new records without upsert capability, so if Attio's email sync has already populated People and Company records, the migration will produce duplicates that must be manually reconciled.

API Rate Limit Management

An API-based migration must manage rate limits on both the Salesforce Bulk API 2.0 extraction side and the Attio REST API loading side, requiring robust error handling, retry logic, and pagination management.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

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

Migration Challenge ClonePartner Status

High Complexity —

Solved

Cases

Cases are not supported by Import2's Salesforce migration path and have no standard Attio object equivalent, requiring a custom object to be created and populated via API.

Solved

Activities (Tasks, Events, Emails)

Tasks can be imported via Import2 but Emails and Meetings are not supported, and Attio's CSV importer cannot import notes, making comprehensive activity history migration dependent on API-based custom work.

Solved

Custom Objects

Salesforce custom objects must be recreated as Attio custom objects with manually mapped attributes, and neither CSV import nor Import2 handles custom object migration, requiring API-based loading.

Solved

Formula and Roll-Up Fields

Attio has no formula field or roll-up summary capability, so all computed values must be extracted as static snapshots from Salesforce and stored as plain attributes, losing their dynamic nature.

Solved

Custom Engineering —

Handled

Leads

Salesforce Leads have no separate equivalent in Attio and must be imported as People or Contacts, requiring decisions about converted vs. unconverted lead handling and potential duplicate creation.

Handled

Opportunities / Deals

Opportunities map to Attio Deals but require three mandatory fields (deal name, owner, stage) and any missing value blocks the entire row during import, plus stage mappings must be manually configured.

Handled

Notes and Attachments

Notes and Attachments are supported by Import2, but Calls are converted to Notes, and file attachments require careful handling of size limits and association to the correct parent records.

Handled

Campaigns

Salesforce Campaigns and Campaign Members have no direct Attio equivalent and must be restructured as Attio lists or custom objects with relationship attributes linking to People and Company records.

Handled

Clean Transfer

Accounts / Companies

Salesforce Accounts map directly to Attio Companies with straightforward field mapping, though Record Type distinctions must be converted to list memberships or status attributes.

Clean

Contacts / People

Contacts map to Attio People with email as the natural unique identifier, making deduplication and relationship linking relatively straightforward.

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 Salesforce 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:

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 Salesforce data and Attio
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 Salesforce 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:

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.
