Overview
Moving from ConvergeHub to Twenty CRM is a migration from a closed, legacy SMB platform to an open-source modern CRM with significantly lower per-seat pricing. ConvergeHub provides no documented public REST API, so all data extraction proceeds via module-level CSV exports from the platform UI. We clean each CSV for encoding issues, reconstruct the Account-to-Contact-to-Opportunity relationship graph using foreign key resolution, and load into Twenty's REST API using batch chunking and retry logic. Twenty CRM's People object consolidates ConvergeHub's separate Leads and Contacts modules. Cases map to Tasks or a custom support object depending on Twenty version maturity. Invoices, Targets, and Quotations migrate as custom objects or are flag-held if the customer prefers to adopt a dedicated accounting tool in parallel. Automation rules, custom modules, and ConvergeHub-specific tooling do not migrate; we deliver a structured inventory of these for the customer's admin to rebuild in Twenty's configuration layer.

Object mapping
Each row shows how a ConvergeHub 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.
ConvergeHub
Lead
Twenty CRM
Person (personType = Lead)
1:1ConvergeHub Leads map to Twenty CRM Person records with personType set to Lead. The Lead's status, source, assignment, and any custom fields migrate as typed fields in Twenty. Email, phone, address, and company name fields map directly. If the Lead has an associated Account in ConvergeHub, we preserve the company reference as a link to a Twenty Company record created from the same Account.
ConvergeHub
Contact
Twenty CRM
Person (personType = Contact)
1:1ConvergeHub Contacts map to Twenty CRM Person records with personType set to Contact. Standard fields (name, email, phone, role, lifecycle stage) map to Twenty's name, email, phoneNumber, and jobTitle fields. The Contact-to-Account linkage migrates as a Company lookup. If ConvergeHub lifecycle stage values exist, they migrate to a custom field on the Person record for reporting continuity.
ConvergeHub
Account
Twenty CRM
Company
1:1ConvergeHub Accounts map directly to Twenty CRM Company records. Industry, size, address, and custom properties migrate as typed fields. Account IDs are preserved in a reference field during staging so that all downstream Contact and Opportunity links resolve correctly. The Company record is created before any Person or Opportunity import to satisfy the required lookup dependency.
ConvergeHub
Deal
Twenty CRM
Opportunity
1:1ConvergeHub Deals map to Twenty CRM Opportunity records. Stage, value, probability, expected close date, and owner assignment migrate directly. Pipeline stage mapping requires a configuration step in Twenty's workspace settings to match ConvergeHub's stage names to Twenty's Opportunity status options. Deal owner resolves to a Twenty User by email match.
ConvergeHub
Deal Stage / Pipeline
Twenty CRM
Opportunity Status + Workspace Customization
lossyEach ConvergeHub pipeline becomes a distinct set of Opportunity status values in Twenty. We extract all pipeline names and stage values from ConvergeHub's pipeline configuration, then configure Twenty's Opportunity object with matching status options before migration. Stage probability percentages are stored as a custom field if the customer requires them for forecasting.
ConvergeHub
Case
Twenty CRM
Task (or Custom Object: Case)
lossyConvergeHub Cases map to Twenty CRM Tasks with the case's subject, status, priority, and description fields migrated. If the customer requires a dedicated support object (separate from sales Tasks), we pre-create a Case custom object in Twenty during schema design, map the case fields accordingly, and link each Case to the originating Person and Company via lookups. The choice is made during scoping based on the customer's support workflow maturity.
ConvergeHub
Invoice
Twenty CRM
Custom Object: Invoice
lossyConvergeHub Invoice records, including line items, totals, tax, and payment status, migrate to a custom Invoice object we create in Twenty's workspace. Invoice-to-Deal links are preserved as Opportunity lookups. Partially paid invoices and payment gateway transaction history do not migrate; we flag these for the customer's admin to reconcile against the source accounting system post-migration.
ConvergeHub
Product
Twenty CRM
Custom Object: Product
1:1ConvergeHub Products (name, SKU, unit price, description) migrate to a Twenty custom Product object. Product associations to Deals are preserved via linked Opportunity records. If Twenty's native product catalog is available at the time of migration, we map to the native object instead of a custom object.
ConvergeHub
Quotation
Twenty CRM
Custom Object: Quotation
lossyConvergeHub Quotations carry product line items, pricing, and terms linked to Deals. We migrate quotation records and their line items to a custom Quotation object in Twenty, preserving the Opportunity lookup. If the customer adopts Twenty's native opportunity features for quotation management, we map to Opportunity instead during the scoping phase.
ConvergeHub
Activity (Call, Task, Event)
Twenty CRM
Task or Event
1:1ConvergeHub Activities linked to Contacts, Leads, Deals, or Accounts migrate as Twenty Tasks with the activity type stored as a custom field. Call disposition, duration, and notes migrate to custom Task fields. Meeting activities migrate as Twenty Events with start time, end time, and location preserved. Each activity's associated Person or Opportunity link is resolved using the foreign key mapping constructed during the staging phase.
ConvergeHub
Document
Twenty CRM
Attachment (via URL reference)
1:1ConvergeHub documents and file attachments are downloaded from the platform UI, re-uploaded to Twenty's workspace file storage, and linked via URL reference to the parent record (Person, Company, or Opportunity). File metadata (name, type, size, upload date) migrates as a structured attachment record. Large binary attachments are handled in batches to avoid timeout during the upload phase.
ConvergeHub
User
Twenty CRM
User
1:1ConvergeHub User records (name, email, role, ACL assignment) migrate to Twenty Users. Role names are mapped to Twenty's permission model during schema design. Owner assignments on Deals, Cases, and Activities resolve by matching ConvergeHub owner email to the Twenty User email after User records are present in the destination.

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.
ConvergeHub gotchas
No public API for automated data extraction
Automation rules cannot be migrated automatically
Custom field types and picklist values need explicit mapping
Lifetime deal data portability is unknown
Account-Contact-Deal relationship chains must be preserved manually
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
Discovery and scoping
We audit the ConvergeHub portal across all active modules: Leads, Accounts, Contacts, Deals, Cases, Invoices, Products, Activities, Documents, and Custom Fields. We capture the complete list of ConvergeHub pipelines and stages, custom field definitions with data types and picklist values, active user count, and any AppSumo licensing tier that may affect export capabilities. The discovery output is a written migration scope document listing all record counts per module, a preliminary object mapping table, and a list of any ConvergeHub automations that require documentation for manual rebuild.
CSV extraction and staging
We extract CSV files per ConvergeHub module directly from the platform UI, running staged exports for modules with more than 5,000 records to avoid timeout. Each CSV is cleaned for encoding issues, empty required fields are flagged for manual resolution, and foreign key ID columns are preserved in a separate staging table for relationship reconstruction. We generate a data quality report identifying duplicates, incomplete records, and records with missing required fields before transformation begins.
Twenty workspace configuration
We configure the Twenty CRM workspace before data loads begin. This includes creating any custom objects (Invoice, Quotation, Product) in Twenty's data model, adding custom fields on Person and Company to carry ConvergeHub metadata, configuring Opportunity status values to match ConvergeHub pipeline stages, and setting up the Twenty User records to match the ConvergeHub user list. Configuration is validated in Twenty's test environment before production migration begins.
Sandbox migration and reconciliation
We run a full migration into a Twenty test workspace using production-like data volume. The customer's team reviews a reconciliation report comparing record counts in ConvergeHub against Twenty, spot-checks 25-50 records for field-level accuracy, and validates that relationship links (Person-to-Company, Opportunity-to-Person, Activity-to-Person) render correctly. Any mapping corrections are applied to the migration scripts before the production migration phase begins.
Production migration in dependency order
We run production migration in record-dependency order: Twenty Users first (validated against the ConvergeHub user list), then Companies (from ConvergeHub Accounts), then Persons (Leads and Contacts with Company lookups resolved), then Opportunities (with Person and Company lookups and owner assignment resolved), then custom objects (Invoice, Quotation, Product), then Activities (Tasks and Events via Twenty's REST API with batch chunking and retry logic). Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation handoff
We freeze ConvergeHub writes during the cutover window, run a final delta migration of any records modified during the migration window, then enable Twenty CRM as the system of record. We deliver the automation capture document listing every ConvergeHub automation with its trigger, conditions, and actions, plus a recommended rebuild approach. We support a five-day hypercare window where we resolve reconciliation issues raised by the customer's team. We do not rebuild ConvergeHub automations inside the migration scope; that is a separate engagement.
