Overview
Simply CRM is a SugarCRM Professional fork with a REST API using objectTypeId 'x' objectId notation for record references. Standard objects include Contacts, Companies, Deals, Activities, and Tasks with configurable custom fields. Twenty CRM runs on React, Node.js, and PostgreSQL with a GraphQL API layer; it models contacts as People, accounts as Companies, and deals as Opportunities. The migration carries Simply CRM's Contact properties, Company records, Deal pipelines with stages, and activity history into Twenty's relational schema, using email-based owner resolution and unique-field referencing for relationship reconstruction. Workflows, sequences, and automations have no equivalent in Twenty's current workflow builder — we export those definitions for your admin to rebuild. The migration runs via Simply CRM's REST query endpoints with result batching, mapping output to Twenty's CSV import format or direct GraphQL mutations depending on record volume. Data integrity checks run throughout the process, flagging any records with missing required fields or broken relationship references before final commit to your Twenty workspace.
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 Simply CRM 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.
Simply CRM
Contact
Twenty CRM
People
1:1Simply CRM Contact records map to Twenty People. Name fields split into firstName and lastName on the Twenty side. Email, phone, and jobtitle transfer directly. The company_id field becomes a companyId relation — the related Company must exist in Twenty first, which is why Companies migrate before People.
Simply CRM
Company
Twenty CRM
Company
1:1Simply CRM Company maps to Twenty Companies with full field parity for name, domain/website, industry, numberofemployees, and annualrevenue. Parent-company hierarchy in Simply CRM (parentid field) maps to a self-referential relation in Twenty using the same parent-company ID logic. Address fields consolidate into a single address string or remain split if Twenty's workspace uses the multi-field format.
Simply CRM
Deal
Twenty CRM
Opportunity
1:1Simply CRM Deal records transfer to Twenty Opportunities. Deal name, amount, closedate, and stage map to opportunityName, amount, closeDate, and stage respectively. The owner_id resolves by matching Simply CRM user emails to Twenty Workspace Member emails. Deal pipeline and probability values migrate as-is; stage-entered timestamps are preserved as custom datetime fields for reporting continuity.
Simply CRM
Activity (Call, Email, Meeting)
Twenty CRM
Task
1:1Simply CRM call and email activities become Twenty Tasks with Type set to 'Call' or 'Email' and Subject carrying the original activity description. Meeting activities map to Twenty Tasks with type 'Meeting' and startDate/endDate from the Simply CRM activity timestamps. The parent_id field links back to the related Contact or Deal record using Twenty's relation model.
Simply CRM
Note
Twenty CRM
Note
1:1Simply CRM Notes transfer as Twenty Notes. Body text, create date, and owner_id map directly. Notes attach to the same parent record (Contact, Company, or Deal) via Twenty's relation system. Rich-text formatting in Simply CRM notes is preserved as plain text in Twenty's Note body.
Simply CRM
User
Twenty CRM
WorkspaceMember
1:1Simply CRM Users resolve to Twenty Workspace Members by email address. If a Simply CRM user email has no matching Twenty member, records are assigned to a fallback owner specified by the customer before migration. This prevents orphaned records where Opportunity or Task owner fields would otherwise be null.
Simply CRM
Pipeline
Twenty CRM
Opportunity Stage
1:1Simply CRM deal pipelines map to Twenty Opportunity stage pick-list values. Each pipeline stage in Simply CRM becomes a named stage option in Twenty's stage field. Stage order is preserved based on Simply CRM's stage sequence. If Simply CRM has multiple pipelines, all stage names collect into a single Twenty pick-list — your admin decides which stages apply per opportunity type.
Simply CRM
Custom Field (any standard object)
Twenty CRM
Custom Field
1:1Simply CRM custom fields on Contacts, Companies, Deals, or Activities require pre-creation in Twenty at Settings → Data Model before the import runs. Field type mapping: text strings to text fields, numbers to number fields, dates to date fields, and pick-lists to select or multi-select fields. Custom field values on records migrate after the field definition exists in Twenty.
Simply CRM
Custom Module
Twenty CRM
Custom Object
1:1Simply CRM custom modules (if present) transfer to Twenty Custom Objects. The migration creates the equivalent object definition in Twenty's data model, then imports records with their relation fields pointing to People, Companies, or Opportunities. N:N relationships between custom modules use Twenty's relation fields, which support multi-value linking.
Simply CRM
Document / Attachment
Twenty CRM
File / Attachment
1:1Simply CRM document and attachment records referencing files on the platform do not have a direct equivalent in Twenty's current import model. Files are re-uploaded as attachments to the target record in Twenty if they are accessible via the Simply CRM export. Files that are stored only in Simply CRM's internal document management are flagged for manual re-upload after migration.

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.
Simply CRM gotchas
SugarCRM Professional edition gates certain modules
Export discrepancies between screen records and CSV output
Custom field schema varies per installation
Workflow automations do not survive migration
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
Audit Simply CRM schema and extract field metadata via describe operation
FlitStack connects to Simply CRM's REST API using session-based authentication (getchallenge/response scheme). We call the describe operation on all active modules — Contacts, Companies, Deals, Activities, Notes, and any custom modules — to capture field names, data types, pick-list values, and required flags. This produces a field inventory that drives the Twenty schema preparation checklist and the transformation logic for each migration batch. We also run a record count per module so the migration timeline can be scoped accurately before any data moves.
Prepare Twenty workspace: create custom fields, invite members, set up opportunity stages
Before data moves, FlitStack generates a step-by-step setup plan for your Twenty workspace. This includes creating custom fields discovered in the Simply CRM audit that have no direct Twenty equivalent, setting up opportunity stage pick-list values to match Simply CRM deal pipelines, and ensuring all users who own records in Simply CRM are invited as Workspace Members in Twenty so owner email resolution works. We deliver the setup checklist with exact field names, types, and options so your admin completes it without guessing. No records are migrated until this schema is confirmed ready.
Run sample migration with field-level diff on 100-500 records
A representative slice of Simply CRM data — spanning Contacts across different companies, Deals in various stages, and a sample of Activities and Notes — migrates to Twenty first. FlitStack generates a field-level diff comparing source and destination values for every mapped field. You verify that custom field values transferred correctly, stage names rendered in Twenty's pick-list, owner emails resolved to Twenty Workspace Members, and relationship links (companyId, personId) point to the correct records. Any mapping errors surface here before the full run commits. Sample migration results are reviewed in a joint session before proceeding.
Execute full migration in dependency order with delta-pickup window
The full migration runs in the confirmed sequence: Companies, then People with companyId links resolved, then Opportunities with personId and companyId links, then Tasks and Notes with their parent links. FlitStack uses Simply CRM's query endpoint with offset/limit batching to paginate through all records without triggering rate-limit errors. A delta-pickup window of 24-48 hours runs concurrently — any records created or modified in Simply CRM during the cutover are captured and appended to the Twenty import before final reconciliation. The audit log records every operation so rollback is available if record counts or relationship integrity checks fail post-import.
Post-migration validation and workflow rebuild handoff
After the full import, FlitStack runs a reconciliation check comparing Simply CRM record counts per object against Twenty record counts, verifying that relationship links (companyId on People, personId/companyId on Opportunities, taskableId on Tasks) resolved correctly. We surface any orphaned records, duplicate emails, or unmapped pick-list values for your team to resolve. The Simply CRM workflow export (JSON reference file) is delivered alongside the migration report so your Twenty admin has a rebuild starting point. FlitStack support remains available for 30 days post-cutover to address any data discrepancies that surface during daily use.
