Overview
Moving from Sage CRM to Twenty CRM is a structural migration that maps a legacy relational entity model to a modern open-source CRM built on PostgreSQL and GraphQL. Sage CRM exposes data through a SOAP/REST API and a direct SQL backend; Twenty CRM accepts imports via CSV, REST, and GraphQL with a self-hosted or cloud deployment option. We extract from Sage CRM's entity tables, resolve the Company-to-Contact-to-Opportunity foreign-key chain during import sequencing, and map Custom Entities to Twenty's workspace-level custom objects. Workflow rules, ASP-scripted actions, and escalation triggers embedded in Sage CRM's database do not export as portable configuration and must be documented for manual rebuild in Twenty. Communication history (emails, call logs, meeting notes) stored in the Communication table migrates as linked activity records against the resolved Contact or Company in Twenty.
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 Sage 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.
Sage CRM
Company
Twenty CRM
Company
1:1Sage CRM Companies map directly to Twenty CRM Companies. We extract the CompanyID, CompanyName, Address fields, Industry, Classification, and any custom Company fields via SQL query or REST API. The CompanyName becomes the display name in Twenty; we use CompanyID as an external ID for deduplication if the same company appears in multiple contexts. Company is imported first because Contacts and Opportunities carry a PrimaryCompanyLink foreign key that must resolve at import time.
Sage CRM
Contact
Twenty CRM
Contact
1:1Sage CRM Contacts link to Companies via PrimaryCompanyLink. We extract all standard contact fields (name, email, phone, title, address) plus custom Contact fields and preserve the company association by resolving the Sage CRM CompanyID to the Twenty CRM Company UUID created during the Company import phase. Duplicate detection uses email as the primary dedupe key, with an optional secondary check on FirstName + LastName if the customer has duplicate-contact cleanup requirements.
Sage CRM
Lead
Twenty CRM
Person (via Company)
1:manySage CRM Leads are a separate entity from Contacts with their own lifecycle stages, qualification fields (LeadSource, LeadStatus, Rating), and source tracking. Twenty CRM does not have a separate Lead object in the traditional sense — unqualified prospects are handled as Persons attached to a Company with a Lead status field. We map Sage CRM Lead records to Twenty CRM Persons, setting a lead_status custom field or using Twenty's built-in opportunity-stage tracking. The Lead's source and qualification data migrate to custom fields on the Person record.
Sage CRM
Opportunity
Twenty CRM
Opportunity
1:1Sage CRM Opportunities map directly to Twenty CRM Opportunities. We extract pipeline stage, revenue amount, expected close date, probability, owner assignment, and any custom Opportunity fields. Sage CRM's pipeline configuration maps to Twenty's opportunity pipeline with stage names translated to Twenty's stage model. Multi-currency amounts migrate with the currency code preserved in a custom field if Twenty's multi-currency is not enabled.
Sage CRM
Case
Twenty CRM
Task or Custom Object
lossySage CRM Cases (service/ticket object) with severity, status, assignment, and resolution fields map to Twenty CRM Tasks if the customer's service process is simple, or to a custom object (e.g., SupportCase) in Twenty if the case model includes threaded communications and SLA fields. Case-threaded communications stored in the Communication table with a CaseID reference migrate as Comment records linked to the migrated Case. We determine the target during scoping based on case complexity and SLA requirements.
Sage CRM
Communication
Twenty CRM
Comment or Task
1:1Sage CRM Communication records store emails, call logs, and meeting notes linked to entity IDs (Company, Contact, Lead, Opportunity, or Case). Twenty CRM does not have a native Communication equivalent, so we map Communications to a combination of Twenty CRM Comments (on Company, Contact, or Opportunity records) and Tasks (for call logs and meeting notes with timestamps and dispositions). Email body content migrates as a Comment; call logs migrate as a Task with TaskSubtype=Call and duration preserved in a custom field. CommunicationDate becomes the ActivityDate or Comment creation timestamp.
Sage CRM
Custom Entity
Twenty CRM
Custom Object
lossySage CRM Custom Entities (user-defined tables with their own fields and relationships) map to Twenty CRM Custom Objects. Each Custom Entity has an internal table name (e.g., CustomEntityname) that differs from its UI display name — we cross-reference the API model service with the UI to build an accurate entity map. Custom Entity fields migrate as Twenty custom fields on the corresponding Custom Object. Custom Entity relationships that reference Companies, Contacts, or Opportunities migrate as lookup fields in Twenty. The customer defines the Custom Object name during scoping.
Sage CRM
User
Twenty CRM
WorkspaceMember
1:1Sage CRM Users with role-based security profiles map to Twenty CRM WorkspaceMembers. We extract UserID, email, name, and active status. Role assignments (SecurityProfile) are documented as a written mapping to Twenty CRM workspace roles during scoping since the permission model differs structurally. Inactive Sage CRM users migrate as inactive WorkspaceMembers to preserve historical assignment records without granting active access.
Sage CRM
Report
Twenty CRM
N/A
lossySage CRM Reports stored in the report schema with entity field references by internal IDs do not migrate as functional reports. We export report definitions, data sources, and scheduling configuration as a written inventory. The customer recreates key reports in Twenty CRM's reporting interface or connects a BI tool (Metabase, Grafana, or a data warehouse) to the Twenty PostgreSQL database for complex reporting needs.
Sage CRM
Workflow Rule
Twenty CRM
N/A
lossySage CRM Workflow rules with ASP-scripted actions, escalation triggers, and approval chains cannot be extracted as portable configuration. We deliver a written workflow inventory documenting every active Sage CRM workflow rule with its trigger conditions, action sequence, escalation configuration, and a recommended Twenty CRM equivalent (manual process, Twenty Workflows beta feature, or a separate automation tool). The customer's admin rebuilds the highest-priority workflows post-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.
Sage CRM gotchas
Workflow rules and ASP scripts do not export as data
Email integration requires third-party plugins or is absent
On-premise IIS hangs require manual restart and block migration
Custom Entities use unique internal naming conventions
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 source Sage CRM deployment (cloud or on-premise), API availability, and data volume across Companies, Contacts, Leads, Opportunities, Cases, Communications, and Custom Entities. We inspect the entity schema via the API model service to map Custom Entity internal names to display names. We document active workflow rules, escalation configurations, and ASP-scripted actions for the workflow inventory. We also assess the destination Twenty CRM deployment (self-hosted or Twenty Cloud) and confirm the import method (CSV, REST, or GraphQL) based on volume. The discovery output is a written migration scope document and a custom entity mapping table.
Destination schema design
We design the Twenty CRM destination schema based on the scoping findings. This includes provisioning any required Custom Objects, custom fields (mapped by type from Sage CRM field definitions), and workspace roles mapped from Sage CRM security profiles. If Sage CRM Cases have complex SLA or threaded-communication requirements, we configure a SupportCase Custom Object. We define the Lead-to-Person mapping strategy (whether leads become Twenty Persons with a lead_status field or a custom Lead object) and document it in the schema design. The schema is deployed to a staging Twenty CRM instance for validation before production migration begins.
Data extraction and staging
We extract data from Sage CRM in dependency order using the most reliable path available: REST API for cloud deployments, direct SQL query for on-premise deployments with database access, or SOAP API as a fallback. Company records extract first, followed by Contact records with PrimaryCompanyLink resolution, then Leads, Opportunities, Cases, and Custom Entities. Communication records extract last in a separate batch because they require entity-type and entity-ID resolution for each row before import into Twenty's typed model. We stage all data in CSV format with external ID columns for deduplication and parent-record lookup.
Sandbox migration and reconciliation
We run a full migration into a staging Twenty CRM instance using production-like data volume. The customer's team reconciles record counts, spot-checks 25-50 records across each object against the Sage CRM source, and validates that Custom Entity relationships resolved correctly (e.g., that a Contact's linked Company appears correctly in Twenty). Any mapping corrections, missing fields, or entity-resolution errors are documented and corrected before production migration begins. We also validate that Communication records landed on the correct parent records (Company, Contact, or Opportunity) in Twenty.
Production migration in dependency order
We run production migration in record-dependency order: Companies first (establishing the dedupe key and Twenty UUID), then Contacts with CompanyID resolved, then Leads (mapped to Persons with lead_status), then Opportunities with OwnerID and CompanyID resolved, then Cases (as Tasks or Custom Objects), then Custom Entities (last because they often reference standard objects via lookups), and finally Communication records as Comments and Tasks. Each phase emits a row-count reconciliation report before the next phase begins. We use exponential backoff on API calls to handle any rate limiting from the Twenty CRM GraphQL or REST API during bulk imports.
Cutover, validation, and workflow rebuild handoff
We freeze writes to Sage CRM during the cutover window, run a final delta migration of any records modified since the last extraction, then set Twenty CRM as the system of record. We deliver the complete workflow inventory document to the customer's admin team, with each workflow rule documented with its trigger, conditions, actions, and recommended Twenty CRM rebuild approach. We support a one-week hypercare window for reconciliation issues raised by the team. We do not rebuild Sage CRM workflows as Twenty CRM workflows inside the migration scope; that is a separate engagement or an internal admin task.
