Overview
Convert Wire and Twenty CRM both organize data around contacts, organizations, and deals, but their schema conventions differ significantly. Convert Wire typically stores deal data in a flat properties model; Twenty CRM separates People, Companies, and Opportunities as distinct objects with explicit foreign-key relationships (companyId on People, companyId and personId on Opportunities). FlitStack AI sequences the migration so parent records exist before child records — companies land first, then people linked to those companies, then opportunities and tasks — resolving Convert Wire's owner assignment and deal-stage fields into Twenty's assignee relations and stage pick-list values. Activities (notes, calls, tasks) migrate to Twenty's Notes and Tasks objects with original timestamps preserved. Every custom property in Convert Wire must be pre-created as a custom field in Twenty via Settings → Data Model before the import runs; this is a hard requirement in Twenty's CSV import system. Workflows, automations, sequences, and third-party integrations do not migrate and must be rebuilt in Twenty's Workflow Builder or reconnected via API. The migration uses scoped read-only access on Convert Wire and bulk-loads into Twenty via API within the rate-limit window for your Twenty tier.

Object mapping
Each row shows how a Convert Wire object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Convert Wire
Person / Contact
Twenty CRM
People
1:1Convert Wire's person or contact records map directly to Twenty's People object. Each person record must include a companyId linking to a Twenty Company record — if Convert Wire stores no primary company, the person lands unlinked and can be associated manually or via bulk-edit after migration.
Convert Wire
Organization / Company
Twenty CRM
Companies
1:1Convert Wire's organization or company records map 1:1 to Twenty's Companies object. Company records migrate first because Twenty's People import requires a valid companyId for each contact — parent-child hierarchies in Convert Wire map to the Twenty company hierarchy via a parentCompanyId field if that relationship exists.
Convert Wire
Deal / Opportunity
Twenty CRM
Opportunities
1:1Convert Wire deal records map to Twenty Opportunities. The deal's linked organization maps to the Twenty opportunity's companyId; if Convert Wire tracks person associations on deals, those link to the opportunity's personId relations in Twenty. Pipeline stage names from Convert Wire become Twenty opportunity stage pick-list values — these must be configured in Twenty's Data Model before the import.
Convert Wire
Pipeline / Pipeline Stage
Twenty CRM
Opportunity Stage
1:1Convert Wire pipeline definitions and their stage names require value-by-value mapping to Twenty's Opportunity stage options. Each distinct Convert Wire stage name creates a corresponding Twenty pick-list value; if Convert Wire supports weighted probability per stage, those percentages map to the stage's probability field on the Twenty opportunity record.
Convert Wire
Task / Activity
Twenty CRM
Tasks
1:1Convert Wire task records migrate to Twenty Tasks. The task title, description, due date, and completion flag transfer directly. Each migrated task links to the appropriate People, Company, or Opportunity record via relation fields that mirror Convert Wire's parent object. Assignee resolution maps the Convert Wire assignee to a Twenty WorkspaceMember by matching email addresses; any assignee without a matching email is flagged for admin review before the migration commits.
Convert Wire
Note / Call Log / Email Log
Twenty CRM
Notes
1:1Convert Wire note records, call logs, and email log entries migrate to Twenty Notes with their rich-text body and original create timestamp preserved. Notes in Twenty can be linked to People, Companies, or Opportunities via relation fields — the parent object type in Convert Wire determines the relation target in Twenty.
Convert Wire
File / Attachment
Twenty CRM
Files
1:1Convert Wire file attachments and inline images stored on records have no direct equivalent in Twenty's standard import flow. FlitStack exports files from Convert Wire's storage and re-uploads them to Twenty's file storage, linking each file to the relevant People, Company, or Opportunity record. Files exceeding Twenty's storage limits are flagged for manual handling.
Convert Wire
Custom Object
Twenty CRM
Custom Object
1:1Convert Wire custom objects migrate to Twenty custom objects. Twenty requires all custom object schemas to be created in Settings → Data Model before the import begins — custom objects are defined via metadata API calls, then data is loaded via CSV or bulk API. Custom-object relationships that use N:N links in Convert Wire need junction objects in Twenty's relational model.
Convert Wire
Owner / Assignee
Twenty CRM
WorkspaceMember
1:1Convert Wire owner or assignee references resolve to Twenty WorkspaceMembers by matching the owner's email address. If a Convert Wire owner has no corresponding email in Twenty, their records assign to a fallback WorkspaceMember or remain flagged for manual reassignment after migration.
Convert Wire
Timestamp / Created Date
Twenty CRM
createdAt / updatedAt
1:1Twenty's native createdAt timestamp reflects the migration import date, not the original Convert Wire record creation date. FlitStack preserves the original Convert Wire created_at and updated_at values as custom datetime fields on each Twenty record (Original_Created_Date__c and Original_Updated_Date__c) so reporting continuity is maintained.
Convert Wire
Record ID / Source System Reference
Twenty CRM
id / sourceSystemId
1:1Convert Wire's internal record IDs are stored on each migrated Twenty record as a custom text field (Source_System_ID__c). This enables FlitStack's delta-run logic to de-duplicate records on subsequent migration passes and allows support teams to trace a Twenty record back to its Convert Wire origin.
Convert Wire
Workflow / Automation
Twenty CRM
Workflow Builder
1:1Convert Wire workflows, sequence rules, and automation triggers do not have a functional equivalent in Twenty's migration layer. These must be rebuilt in Twenty's Workflow Builder after the data migration completes. FlitStack exports Convert Wire workflow definitions as a structured reference document for the rebuilding team.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Convert Wire gotchas
Convert Wire is a service, not software — no platform to migrate from
No documented API or integration endpoint
Caller-captured data lives in Convert Wire's internal systems
Proprietary target lists do not transfer
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Prepare Twenty workspace schema
Before any data moves, FlitStack audits the Convert Wire data model — identifying standard fields, custom properties, and any custom objects — and maps each one to a corresponding Twenty field. For every Convert Wire custom property, we deliver a schema setup checklist: create this custom field in Settings → Data Model, set the field type, configure pick-list options for stage-like fields, and invite all team members to Twenty so user relations can resolve during import. This step ensures the Twenty workspace is schema-ready before the first CSV is uploaded.
Export Convert Wire data per object type
FlitStack connects to Convert Wire via its export API (CSV or bulk export format depending on Convert Wire's available endpoints at the time of migration). We export each object type separately — People, Companies, Deals, Tasks, Notes, and any custom objects — including every standard and custom field, timestamps, and owner references. The export runs with read-only access; Convert Wire remains fully operational for your team during this phase.
Map fields and transform data
Each Convert Wire field maps to its Twenty equivalent. Direct mappings (email → email, name → name) transfer as-is. Fields requiring transformation — such as Convert Wire owner_id resolving to Twenty WorkspaceMember by email, or currency-formatted amounts stripping the currency symbol — are handled in FlitStack's staging layer. Custom fields that were pre-created in Step 1 map by name match. Every record receives a Source_System_ID__c value for delta-run traceability.
Run a sample migration and generate a field-level diff
FlitStack runs a representative slice of records — typically 100 to 500 across People, Companies, and Deals — into Twenty and generates a field-level diff report. This report shows every mapped field, its source value in Convert Wire, and the resulting value in Twenty. You can verify that stage names, owner assignments, custom field values, and company links resolved correctly before the full migration commits. Any mapping errors are corrected before the next step begins.
Execute full migration with delta-pickup cutover window
The full dataset migrates into Twenty following the import-order sequence (Companies → People → Deals → Tasks/Notes → Custom Objects). A delta-pickup window — typically 24 to 48 hours — captures any records created or modified in Convert Wire during the migration run. FlitStack generates a post-migration audit log documenting record counts, any errors, and the mapping decisions made for edge cases. One-click rollback is available if reconciliation against the Convert Wire source reveals discrepancies.
