Overview
Moving from Attio to Zoho CRM is a schema-first migration. Attio's flexible object model lets teams define custom objects with arbitrary attributes; Zoho CRM uses a fixed module structure (Contacts, Accounts, Potentials, Tasks) with Custom Modules for extensions. We handle the translation by auditing every Attio object and attribute, creating matching Zoho Custom Modules with the appropriate field types before any data writes, and resolving relationship chains (which Attio's flat CSV exports do not preserve) through direct API queries. Lists, Sequences, and Workflows do not migrate as functional code; we deliver a written inventory of these for the customer's Zoho admin to rebuild using Zoho's Blueprint and workflow automation tools. The migration is staged through Zoho's Data Migration Wizard for standard modules and through the API for Custom Modules that exceed the wizard's module mapping scope.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Attio object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Attio
People
Zoho CRM
Contact
1:1Attio People records map directly to Zoho CRM Contacts. All standard Attio attributes (name fields, email, phone, title, address) map to Zoho Contact standard fields. Custom attributes on People migrate to Zoho Custom Fields created during schema pre-build. Email addresses serve as the dedupe key during import so duplicate records are resolved rather than duplicated.
Attio
Company
Zoho CRM
Account
1:1Attio Company records map to Zoho CRM Accounts. The Attio domain attribute becomes the Account Website field. Accounts are imported before Contacts so that the Account-Contact lookup relationship is satisfied at the moment of Contact insert. Many-to-many relationships between Companies and People in Attio (where one Person can link to multiple Companies) are preserved as secondary Account lookups on the Contact record.
Attio
Deal
Zoho CRM
Potential
1:1Attio Deals map to Zoho CRM Potentials. The Attio dealstage property maps to the Zoho Stage field, and pipeline assignment maps to a Zoho Sales Pipeline configured before migration. Deal amount, closing date, currency, and owner assignment transfer directly. Attio's Deal-to-Company relationship maps to the Potential's Account Name lookup.

Deal Stage
Zoho CRM
Potential Stage + Sales Pipeline
lossyEach Attio pipeline becomes a Zoho Sales Pipeline with corresponding stage names. We pre-create the pipeline in Zoho with the exact stage sequence from Attio before any Potential records are written. Probability percentages map from Attio to Zoho stage probability fields.
Attio
Custom Objects
Zoho CRM
Custom Modules
1:1Attio custom objects (Subscriptions, Projects, Investors, Partnerships) map to Zoho Custom Modules. We pre-create the Zoho module with all fields, field types, and lookup relationships matched to the Attio attribute types during the schema design phase. Gated plan validation: if the source workspace uses more objects than Zoho Standard supports (500 Custom Fields per module), we recommend Professional tier before migration begins. Attio relationship attributes on custom objects become Zoho Lookup fields.
Attio
Relationship Attributes
Zoho CRM
Lookup Fields + Related Lists
1:1Attio relationship attributes define how records across objects link together (Deal linked to Company and multiple People). These do not appear in Attio's flat CSV export — we query them via the Attio API to reconstruct parent-child chains. Each relationship chain is resolved by matching on record ID and email, then written to Zoho as a Lookup field on the related module. Many-to-many relationships become Zoho linking modules (junction objects) so both sides can query the relationship without data duplication.
Attio
Lists
Zoho CRM
Custom Fields + Tags (reconstruction)
lossyAttio Lists are workflow-context collections of record entries, not standalone records. Zoho CRM has no native List equivalent. We extract list memberships via the Attio API, reconstruct them as a combination of Zoho Tags (applied to Contacts and Accounts) and a custom picklist field (List Name) so the segmentation logic is visible in Zoho reports and filters. The customer reviews the reconstructed list structure before migration commits.
Attio
Notes
Zoho CRM
Notes
1:1Attio Notes attach to records as first-class API objects with timestamps and author attribution. They migrate to Zoho Notes attached to the corresponding Contact, Account, or Potential record. Note body content transfers as plain text. If Attio Notes contain file attachments, these migrate as Zoho Attachments linked to the same parent record.
Attio
Tasks
Zoho CRM
Tasks
1:1Attio Tasks migrate to Zoho Tasks with Status, Priority, Due Date, and Activity Date preserved. Task assignment migrates by resolving the Attio owner reference to a Zoho User record via email match. Tasks attached to specific records carry the Zoho Related To lookup for the parent Contact, Account, or Potential.
Attio
Users
Zoho CRM
User
1:1Attio User records represent team members referenced as owners on Contacts, Companies, and Deals. We resolve owners by matching Attio user email to Zoho User email. Any Attio Owner without a matching Zoho User goes to a reconciliation queue for the customer's admin to provision before record import proceeds, because Zoho requires a valid OwnerId reference on Contact and Potential records.
Attio
Activities: Emails and Meetings
Zoho CRM
Activities + Notes (timeline reconstruction)
1:1Attio's automatic email and calendar sync attaches to People and Company records only. Imported email and meeting history is treated as read-only timeline entries in Zoho. We reconstruct them as Zoho Activity records linked to the Contact or Account, with a custom field capturing the original Attio timestamp for historical ordering. Manual activity logs (calls, meetings logged by reps) migrate as Zoho Tasks with Activity type distinction preserved.
Attio
Workflows
Zoho CRM
Blueprint + Workflow Rules (documented, not migrated)
lossyAttio Workflows consume workspace credits and are gated by plan tier. They do not migrate as functional code because Attio's trigger-action model differs structurally from Zoho's Blueprint and Workflow Rule architecture. We extract every active Attio Workflow and deliver a written document mapping each trigger, condition, and action to its Zoho equivalent. The customer's Zoho admin or a Zoho implementation partner rebuilds them post-migration.

Migration approach
Discovery and schema audit
We audit the source Attio workspace across plan tier (Free/Plus/Pro/Enterprise), object count, custom attribute types, active workflows, and relationship attribute count. We also review Zoho's destination plan and identify any field-type mismatches between Attio's flexible schema and Zoho's constrained Custom Module field types. The discovery output is a written migration scope document that lists every Attio object, its Zoho destination module, field-level mappings, and any attributes that require custom field creation or type conversion before import.
Zoho Custom Module schema pre-build
We build the Zoho destination schema before any data is extracted from Attio. This includes creating Custom Modules for any Attio custom objects, adding all custom fields with the appropriate Zoho field types, configuring Lookup fields for every relationship chain, and setting up Sales Pipelines with matching stage sequences. Schema is validated in a Zoho sandbox or staging environment first. This step prevents the common failure mode where data arrives before the target field exists, causing silent type coercion or import errors.
Relationship chain extraction via Attio API
We extract every Attio relationship attribute via the API — Deal-to-Company links, Company-to-People associations, and any custom object relationships. These are stored as a separate lookup table keyed by Attio record ID, which is used during the Zoho import phase to write the correct Lookup field values rather than relying on CSV flat-file join keys that do not exist in the Attio export.
Owner reconciliation and Zoho User provisioning
We extract every distinct Attio Owner referenced on Contacts, Companies, Deals, and Tasks and match by email against the Zoho destination User table. Owners without a matching Zoho User are placed in a reconciliation queue. The customer's Zoho admin provisions any missing Users in Zoho before the migration moves to record import. This step is required because Zoho's Contact and Potential records require a valid OwnerId reference and will fail import if the owner email has no corresponding Zoho User.
Staged import in dependency order
We run the migration in strict dependency order: Accounts (from Attio Companies) first, then Contacts with AccountId resolved from the lookup table, then Potentials with AccountId and ContactId resolved, then Tasks and Notes, then Custom Modules last. Each phase emits a row-count reconciliation report comparing the Attio source count to the Zoho destination count before the next phase begins. Relationship chains are written after the parent records are confirmed in Zoho so that Lookup fields are populated, not null.
Cutover, validation, and Workflow rebuild handoff
We freeze writes in Attio during the final cutover window, extract any delta records modified during migration, then complete the Zoho import. We deliver a Workflow and Sequence inventory document listing every active Attio Workflow with its trigger, conditions, and actions mapped to Zoho Blueprint or Workflow Rule equivalents. We do not rebuild Attio Workflows as Zoho automations inside the migration scope. We support a one-week post-cutover window for reconciliation issues. Training, onboarding, and ongoing Zoho admin configuration are separate engagements.
