Overview

What this migration involves

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.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Sage CRM

What's pushing teams away

  • The interface and feature set lag behind modern cloud CRMs — users report that HubSpot, Salesforce, and Zoho CRM offer more frequent updates and richer out-of-the-box functionality.
  • Email integration is weak and requires third-party plugins or manual configuration; users cannot natively sync email, calendar, or tasks without additional cost.
  • Performance issues including IIS hangs and slow database queries force periodic restarts that interrupt daily users, especially on on-premise deployments.
  • The learning curve is steeper than expected for non-technical users, and the ASP-based customization layer requires developer involvement for anything beyond basic configuration.
  • Workflows, custom scripts, and ASP components are not portable during migration — teams must rebuild their automation logic from scratch in the new CRM.

Choosing

Twenty CRM logo

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Sage CRM objects map to Twenty CRM

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

maps to

Twenty CRM

Company

1:1
Fully supported

Sage 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

maps to

Twenty CRM

Contact

1:1
Fully supported

Sage 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

maps to

Twenty CRM

Person (via Company)

1:many
Fully supported

Sage 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

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Sage 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

maps to

Twenty CRM

Task or Custom Object

lossy
Fully supported

Sage 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

maps to

Twenty CRM

Comment or Task

1:1
Fully supported

Sage 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

maps to

Twenty CRM

Custom Object

lossy
Fully supported

Sage 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

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

Sage 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

maps to

Twenty CRM

N/A

lossy
Fully supported

Sage 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

maps to

Twenty CRM

N/A

lossy
Fully supported

Sage 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.

Pair-specific challenges

  • Sage CRM workflows and ASP scripts are not portable

    Sage CRM workflows are stored as database records containing embedded ASP-script logic, escalation triggers, and action handlers. There is no export mechanism that produces portable automation code. When migrating to Twenty CRM, every active workflow must be documented during discovery and manually rebuilt by the customer's admin using Twenty's visual workflow builder or a third-party automation tool. We produce a complete workflow inventory during scoping that lists every active rule, its trigger, conditions, actions, and escalation path, prioritized by business criticality so the customer knows which five to ten workflows to rebuild first.

  • Custom Entity internal names differ from display names

    Sage CRM Custom Entities have both a UI display name and an internal database table name (e.g., a Custom Entity shown as 'Vehicles' in the UI may have an internal name of 'CustomEntityname'). The REST and SOAP APIs reference entities by their internal name, which is not visible in the standard UI. We inspect the entity schema via Sage CRM's API model service and cross-reference with the UI display name to produce an accurate entity map before migration. Skipping this step results in API calls referencing the wrong entity and failed imports.

  • Communication table has no direct Twenty CRM equivalent

    Sage CRM stores email history, call logs, and meeting notes in the Communication table linked to entity IDs (Company, Contact, Lead, Opportunity, or Case). Twenty CRM does not have a unified Communication object — emails are handled via IMAP/SMTP sync and activity history is stored as Tasks and Comments. We map Communication records to Twenty Comments (for email body content) and Tasks (for call logs and meeting notes). The entity-agnostic nature of the Communication table means we must resolve the entity type and ID for each record before importing into Twenty's typed relationship model.

  • On-premise Sage CRM extraction requires IIS and SQL access

    Self-hosted Sage CRM deployments extract data via the REST/SOAP API (which runs through IIS) or directly from the SQL/Pervasive database. IIS application pool hangs are a known issue with self-hosted Sage CRM and can interrupt a live migration or delay data extraction. We recommend scheduling extraction during low-activity windows, verifying server responsiveness before each migration run, and having a database-read user account provisioned with direct SQL access as a fallback extraction path if the API becomes unavailable during the migration window.

  • Lead entity requires a non-standard mapping to Twenty CRM

    Sage CRM maintains a separate Lead entity with its own lifecycle stages, qualification fields, and source tracking distinct from Contacts. Twenty CRM does not have a traditional separate Lead object — unqualified prospects are represented as Persons with status fields or through opportunity pipeline stages. We map Sage CRM Leads to Twenty CRM Persons, preserving the lead source, qualification status, and rating as custom fields. The customer defines the target representation (Person + pipeline stage vs. custom Lead object) during scoping based on their sales process.

Migration approach

Six steps for a successful Sage CRM to Twenty CRM data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • Tight native integration with Sage accounting products including Sage 50, Sage 100, Sage 300, and Sage X3 for finance-first SMBs.
  • Per-user annual pricing at approximately $590/year is competitive for small teams compared to Salesforce or HubSpot entry points.
  • On-premise deployment option provides data residency and sovereignty for companies with IT infrastructure staff already in place.
  • Workflow engine supports multi-step approval chains and automated stage transitions without requiring developer involvement for basic rules.
  • SQL/Pervasive database backend allows direct database extraction for high-volume exports when the API is insufficient.

Weaknesses

  • Email, calendar, and task integration requires third-party plugins or manual Outlook configuration, unlike natively integrated competitors.
  • The ASP-based customization layer means non-trivial customizations require a developer and are not self-service.
  • Workflow and automation logic cannot be exported and must be rebuilt manually in any replacement CRM, adding significant post-migration effort.
  • Performance degrades on on-premise deployments with large datasets, requiring periodic SQL maintenance and occasional IIS restarts.
  • Feature development cadence is slow compared to cloud-native CRMs, leaving Sage CRM users on an increasingly dated interface and toolset.

Strengths

  • AGPL-3.0 open-source license with full source code on GitHub — no vendor lock-in, no sunset risk.
  • Unlimited users and unlimited custom objects on self-hosted, with no feature gating based on headcount.
  • REST and GraphQL APIs available on all paid tiers, not locked behind an enterprise add-on fee.
  • MCP server and webhooks shipped as standard features, not premium upgrades.
  • Modern PostgreSQL-backed data model that developer teams can query, extend, and self-host.

Weaknesses

  • Recent v1.0 release means limited production hardening compared to CRMs with multi-year operational track records.
  • No native email sequencing or sales engagement tools — follow-up cadences require a separate platform.
  • No native two-way email sync or inbox integration, requiring third-party connectors for full activity logging.
  • Self-hosting 'free' pricing hides real infrastructure and DevOps costs that stack up over time.
  • Workflow automation is functional but lacks the complexity needed for sophisticated multi-step sales motions.
