Overview
Moving from FIVE CRM to Twenty CRM is a telemarketing-to-open-source transition that surfaces a fundamental schema difference: FIVE CRM ships with telemarketing-specific fields pre-built (lead scoring, campaign tracking, custom call dispositions) while Twenty CRM provides a minimal standard object model and expects users to build out their data model using its custom field builder. This means every FIVE CRM migration requires a mandatory custom field creation phase in Twenty before any data can land cleanly. We run that schema build using FIVE CRM's exported field inventory, create all custom fields in Twenty Settings before import, then map Contacts to People, Companies to Companies, Deals to Opportunities with campaign membership stored as a custom multi-select field or tag, and Tasks to Tasks. FIVE CRM's opaque system failure messages (which return no diagnostic detail when errors occur) require us to extract data directly from the export endpoint rather than relying on UI feedback. We do not migrate FIVE CRM workflows, email sequences, or campaign engagement event logs; we deliver a written inventory of these for your admin to rebuild in Twenty's workflow builder.

Object mapping
Each row shows how a FIVE 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.
FIVE CRM
Contact
Twenty CRM
People
1:1FIVE CRM Contacts map to Twenty CRM People. Standard fields (name, email, phone, address) transfer directly. FIVE CRM's custom telemarketing fields (lead score, call disposition, last call outcome) require pre-created custom fields in Twenty's Data Model before import; we enumerate these during scoping and create them in Twenty Settings prior to data load. Contact owner resolves by email match against Twenty Members.
FIVE CRM
Company
Twenty CRM
Company
1:1FIVE CRM Companies map to Twenty CRM Companies. Company is created before People import so that the relationship lookup is satisfied at the moment of People insert. FIVE CRM's domain field maps to Twenty's website field and is used as the dedupe key. Custom company fields (industry classification, employee count ranges used in telemarketing segmentation) migrate to pre-created custom fields.
FIVE CRM
Lead
Twenty CRM
People (with type flag) or Opportunity
1:manyFIVE CRM separates Leads from Contacts in its data model. We merge Lead records into Twenty CRM People and set a custom field lead_source__c from FIVE CRM's originating lead source property. If the FIVE CRM Lead has an associated Deal, that Deal migrates to Twenty Opportunity with the Opportunity's primary contact set to the merged People record.
FIVE CRM
Deal
Twenty CRM
Opportunity
1:1FIVE CRM Deals map to Twenty CRM Opportunities. The deal name, amount, expected close date, and pipeline stage transfer directly. FIVE CRM's custom pipeline stages require mapping to Twenty's Opportunity stage values, which we configure as part of the pre-migration schema build. Deal owner resolves by email match against Twenty Members.
FIVE CRM
Pipeline Stage
Twenty CRM
Opportunity Stage
lossyFIVE CRM pipeline stages are tenant-specific custom labels. We capture every active stage label during scoping, map each to a Twenty Opportunity stage value, and configure Twenty's opportunity stage list in Settings before migration. Stage probability percentages transfer where FIVE CRM exposes them; otherwise we set defaults and the customer adjusts post-migration.
FIVE CRM
Campaign
Twenty CRM
Opportunity (with campaign tag) or Custom Object
lossyFIVE CRM Campaign records track email marketing sequences and campaign membership. Campaign membership transfers as a custom multi-select field or tag on the linked Twenty People or Opportunity record, depending on which object the campaign primarily targets. Individual email event logs (opens, clicks) do not have a direct Twenty equivalent and are documented as not migrating.
FIVE CRM
Task
Twenty CRM
Task
1:1FIVE CRM Tasks map to Twenty CRM Tasks with due date, assignee, status, and description preserved. Task assignee resolves by email match against Twenty Members. FIVE CRM task types (call back, follow up, demo scheduled) map to Twenty task categories or custom task type fields created during the schema build phase.
FIVE CRM
User
Twenty CRM
Member
1:1FIVE CRM Users (owner records) map to Twenty CRM Members. We resolve by email match. Any FIVE CRM User without a matching Twenty Member goes to a reconciliation queue for the customer's admin to provision the account in Twenty Settings before record import resumes. Twenty requires Members to be invited and active before owner lookups can resolve.
FIVE CRM
Custom Field
Twenty CRM
Custom Field
lossyFIVE CRM custom fields are tenant-specific and not consistently named across deployments. We enumerate every custom field in use during a pre-migration field mapping session, confirm data types, and create matching fields in Twenty's Data Model before import. FIVE CRM's opaque error system means we cannot always rely on the UI to surface field anomalies, so we validate field types against known FIVE CRM schemas and test each custom field independently during the sandbox migration phase.
FIVE CRM
Tag
Twenty CRM
Tag or Custom Field
lossyFIVE CRM tags label records for segmentation and campaign targeting. We map tags to Twenty's tag system or to a custom multi-select field depending on the tag's semantic role (segmentation tag vs. campaign classification). Multi-select tag fields may split into multiple rows during import if the destination uses a single-select field; we document this during scoping and the customer chooses the strategy.
FIVE CRM
Attachment
Twenty CRM
File
1:1File attachments associated with FIVE CRM Contacts, Companies, or Deals migrate as file references or re-upload depending on the target Twenty deployment. Attachments over 10MB require separate handling due to API upload size constraints. We flag large attachments during scoping and handle them as a post-migration manual upload batch.
FIVE CRM
Campaign Engagement
Twenty CRM
Not migrated (documented)
lossyFIVE CRM tracks email campaign engagement (opens, clicks, replies) at the contact level. Twenty CRM does not expose a granular per-event engagement log object in its standard data model. We migrate campaign membership and status flags to People and Opportunity records; individual email event logs are documented in a separate export for the customer's admin to import manually if the downstream reporting requires it.

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.
FIVE CRM gotchas
System failure errors give no explanation
Custom fields require explicit manual mapping
Campaign engagement history may not transfer completely
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 field inventory
We audit the source FIVE CRM deployment across every active object (Contacts, Companies, Leads, Deals, Pipelines, Campaigns, Tasks), enumerate every custom field in use, confirm data types against known FIVE CRM schemas, and capture the full list of active users and owners. We extract sample records to validate field completeness and identify any tenant-specific naming conventions. This step surfaces the scope of the mandatory Twenty custom field creation phase.
Twenty schema build and member provisioning
We create every FIVE CRM custom field as a typed custom field in Twenty CRM Settings Data Model before any data import. We configure Opportunity stage values mapped from FIVE CRM pipeline stages, set up Company and People custom fields for lead source, campaign membership, and telemarketing disposition data, and invite all team members as Twenty Members by email. We validate that the Twenty Members list is complete and active before proceeding because owner lookups resolve against this list.
Sandbox migration and reconciliation
We run a full migration into a Twenty sandbox environment using production-like data volume. The customer's RevOps lead reconciles record counts (People, Companies, Opportunities, Tasks), spot-checks 25 to 50 random records against the FIVE CRM source, and validates that custom field values populated correctly. Any mapping corrections, missing field creations, or type coercion issues surface here before production migration begins.
Owner and assignee reconciliation
We extract every distinct FIVE CRM owner referenced on Contacts, Companies, Deals, and Tasks and match by email against the Twenty Members list provisioned in step two. Owners without a matching Twenty Member go to a reconciliation queue. The customer's admin provisions any missing Members in Twenty Settings, confirms their active status, and we re-run the match before production migration proceeds.
Production migration in dependency order
We run production migration in record-dependency order: Companies first (to satisfy the People company lookup), then People (with owner resolved), Leads merged into People with lead_source__c preserved, Opportunities (with company lookup and owner resolved), Tasks (with assignee resolved), campaign membership stored as tags or custom fields on the linked record, and custom field values backfilled per field created in step two. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation inventory delivery
We freeze FIVE CRM writes during cutover, run a final delta migration of any records modified during the migration window, then enable Twenty CRM as the system of record. We deliver a written inventory of every active FIVE CRM workflow, campaign sequence, and automation with its trigger, conditions, actions, and a recommended Twenty workflow equivalent. We support a one-week hypercare window where we resolve reconciliation issues. We do not rebuild FIVE CRM workflows as Twenty workflows inside the migration scope; that is documented separately for the customer's admin to implement.
