Overview

What this migration involves

Rainbow CRM has no publicly documented API, so every migration runs from the platform's CSV and JSON export formats. We extract Companies first so that Person imports can resolve company-name matches, then migrate Persons with email deduplication against an existing collision report, then Opportunities with stage labels remapped to Twenty's pipeline conventions. Custom fields present in Rainbow CRM's export schema get pre-created in Twenty via the Settings Data Model UI before any import batch runs. Activities export in a denormalized format and we reconstruct them as Tasks or Notes attached to the correct Person or Company record during import. We do not migrate Rainbow CRM workflows or automations; the written inventory of these is part of the standard handoff package for your admin to rebuild in Twenty's workflow builder. Attachment records do not appear in Rainbow CRM's documented export format and cannot be migrated through this path.

Why teams make this switch

Two sides of the same decision

Leaving

Rainbow CRM

What's pushing teams away

  • Rainbow CRM has no publicly documented API, making integrations with other tools difficult and migration依赖 on manual export formats, per TechnologyCounter specifications.
  • Email-only support with no live chat or phone option frustrates teams that need real-time help during setup, noted across review site listings.
  • No free trial is offered, forcing teams to commit before testing the platform against their actual workflow, per Capterra specs.

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 Rainbow CRM objects map to Twenty CRM

Each row shows how a Rainbow 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.

Rainbow CRM

Company

maps to

Twenty CRM

Company

1:1
Fully supported

Rainbow CRM Companies export as flat records and map directly to Twenty's Company standard object. We import Companies first in every migration batch so that Person imports can satisfy the company-name lookup relationship that Twenty's Person schema supports. The export's company domain field maps to Twenty's website field and is used as a dedupe key if multiple company records share the same domain.

Rainbow CRM

Contact

maps to

Twenty CRM

Person

1:1
Fully supported

Rainbow CRM Contacts map to Twenty's Person standard object. Standard fields (name, email, phone, address) migrate directly. Lifecycle stage is not a native field in Rainbow CRM and will not appear in exports; we create a custom picklist field on Person to capture any customer-defined stage data if present in the export schema. Email deduplication runs at import time against the full Person batch, and duplicate email conflicts are surfaced for customer review before records are committed.

Rainbow CRM

Lead

maps to

Twenty CRM

Person or Lead

1:1
Fully supported

Rainbow CRM Leads export as a separate object but may share email addresses with existing Contacts, creating overlap in Twenty's Person records. We deduplicate at import time by comparing email addresses across the Contact and Lead batches, flagging any duplicate email conflicts for customer review before writing records. If the customer requires a separate Lead pipeline for unqualified prospects, we create a custom Person view filtered by a lead-status field rather than a separate object.

Rainbow CRM

Deal

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Rainbow CRM Deals map to Twenty's Opportunity standard object. The export includes pipeline stage labels in Rainbow CRM's internal naming convention, which do not match Twenty's default Opportunity stages. We present a stage mapping table during scoping and apply the agreed mapping before the first import batch. Closed-won and closed-lost outcomes migrate as Opportunity stage values rather than separate deal-state fields.

Rainbow CRM

Pipeline Stage

maps to

Twenty CRM

Opportunity Stage

lossy
Fully supported

Each Rainbow CRM pipeline becomes a Twenty Opportunity pipeline with its own stage values. We configure the pipeline in Twenty's settings before migration, adding stages that correspond to the exported dealstage labels. Stage probability percentages are mapped from the Rainbow CRM export where present, or set to Twenty defaults for unmapped stages.

Rainbow CRM

Task

maps to

Twenty CRM

Task

1:1
Fully supported

Rainbow CRM Tasks export as flat records without assignee user IDs. We map task titles, due dates, and descriptions directly. Assignee resolution requires a cross-reference against the Twenty workspace Members list after scoping; the customer's admin must invite all team members before migration so that assignee email addresses can be matched to Twenty User records and the TaskAssignee field can be populated.

Rainbow CRM

Activity (denormalized)

maps to

Twenty CRM

Task or Note

1:1
Fully supported

Rainbow CRM exports activity history (calls, emails, meetings, notes) in a denormalized flat format. We reconstruct activity threads by parsing the export, grouping records by contact and timestamp, and creating individual Task records for each engagement event. Call disposition, duration, and meeting location fields map to custom fields on the Task record. Activity ordering is preserved by setting the Task due date and completion date to the original Rainbow CRM timestamp.

Rainbow CRM

Custom Field

maps to

Twenty CRM

Custom Field (on target object)

lossy
Fully supported

Rainbow CRM exposes a subset of custom fields in exports. We inspect the export schema during discovery and flag any custom properties that do not appear in the raw file. For fields that are present, we create matching custom fields in Twenty via Settings Data Model before the import batch runs. Fields must exist in Twenty before CSV import because the import creates records, not fields. This pre-creation step is the most common point of failure in CSV-based migrations and we treat it as a prerequisite.

Rainbow CRM

Custom Object

maps to

Twenty CRM

Custom Object

1:1
Fully supported

Rainbow CRM custom objects export in the same flat format as standard objects if they are present in the export. We create the corresponding custom object in Twenty via the /metadata API, including all custom fields, field types, and any lookup relationships to standard objects. Custom object schema must be deployed before the standard object import so that lookup fields on imported records can resolve to the correct target.

Rainbow CRM

Owner

maps to

Twenty CRM

User

1:1
Fully supported

Rainbow CRM Owner records reference team members on Contacts, Companies, Deals, and Tasks. We extract owner email addresses from the export and match them against the Twenty workspace Members list. Any owner without a matching Twenty User is held in a reconciliation queue; the customer's admin provisions the missing User account before record import resumes. Owner resolution is a dependency gate: no Opportunity or Task import runs until all Owner references can be resolved.

Pair-specific challenges

  • Rainbow CRM export may omit custom fields not guaranteed in schema

    Rainbow CRM's documented export format does not guarantee that all configured custom fields appear in the output file. We inspect the export schema during discovery and compare it against the field inventory the customer expects to migrate. Any gap between the export schema and the customer's expected fields is flagged before we commit to scope. High-value custom fields that do not appear in the export require either a direct database extraction from Rainbow CRM (coordinated with their team) or a manual export of those specific records. If we proceed without this inspection, the migration silently drops custom field values that the customer expected to carry over.

  • Custom fields must exist in Twenty before CSV import runs

    Twenty's CSV import creates records, not fields. Every custom field referenced in your Rainbow CRM export must be pre-created in Twenty via Settings Data Model before any import batch runs. This is a documented Twenty requirement (docs.twenty.com migration guide). If a custom field does not exist in Twenty when the CSV is imported, the import skips that column silently. We treat custom field pre-creation as the first migration step in every Twenty destination, and we validate field existence against the CSV column headers before loading data.

  • Activity history exports denormalized; thread reconstruction required

    Rainbow CRM exports activity records (calls, emails, meetings, notes) in a flat, denormalized format where each engagement may appear as a separate row without an explicit thread identifier. We reconstruct activity threads by grouping records by contact identifier and timestamp, then creating individual Task or Note records in Twenty. This reconstruction step adds processing time and requires a mapping table of engagement type to Twenty Task subtype, which we build during scoping. Migrations with large activity volumes (over 50,000 rows) require batched processing to avoid memory exhaustion during the reconstruction pass.

  • Email deduplication must resolve Contact and Lead overlap before import

    Rainbow CRM exports Contacts and Leads as separate objects, but a single person may appear in both exports with the same email address. Twenty's Person object has no built-in duplicate email prevention during CSV import; inserting a Contact and a Lead with the same email creates two separate Person records with no automatic link. We run an email deduplication pass across the combined Contact and Lead export before any records are written to Twenty, surfacing the conflicts to the customer's admin for resolution (keep Contact, keep Lead, or merge into one Person).

  • Twenty workflow builder lacks native sequencing for manual-trigger flows

    Reddit r/CRM discussions (October 2024) confirm that Twenty CRM's workflow builder does not support native sequencing for manual-trigger flows such as Call then Wait then Email cadences. Teams migrating from Rainbow CRM's campaign management feature should plan to rebuild any multi-step engagement sequences outside Twenty's native automation. Recommended alternatives include external sales engagement tools (Salesloft, Outreach, Apollo) connected via Twenty's GraphQL API, or rebuilding simpler sequences as Triggered Tasks in Twenty's workflow builder without built-in wait logic.

Migration approach

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

  1. Export audit and schema inspection

    We request a full export package from Rainbow CRM during scoping: Companies CSV, Contacts CSV, Leads CSV, Deals CSV, Tasks CSV, and the Activities export if available. We inspect the schema of each file against the field inventory the customer expects to migrate, flag any custom fields that are missing from the raw export, and confirm the dealstage label set for pipeline mapping. We do not commit to migration scope until the export schema matches the customer's expected field coverage. If the export omits required fields, we surface the gap and adjust scope before touching production data.

  2. Twenty workspace preparation and custom field pre-creation

    We create all custom fields in Twenty before any import batch runs. This means going to Settings Data Model and creating every custom field that appears in the Rainbow CRM export but does not exist as a standard Twenty field. For custom objects, we call the /metadata API to provision the object and its fields. We also configure the Opportunity pipeline with stages that correspond to the Rainbow CRM dealstage labels. Finally, we confirm that all team members have been invited to the Twenty workspace and have accepted their invitations, because assignee email matching requires existing User records.

  3. Export transformation and duplicate resolution

    We transform the Rainbow CRM export files into Twenty-compatible CSV format: we rename columns to match Twenty's field names, apply the dealstage mapping table, format dates to ISO 8601, and normalize phone numbers. We run email deduplication across the combined Contact and Lead export and surface conflicts to the customer's admin for resolution before any records are written. We sequence parent records before children: Companies first, then Persons, then Opportunities, then Tasks, then Activities.

  4. Test import into Twenty (dry run)

    We run a full dry-run migration into a fresh Twenty workspace using production record counts. The customer's admin reviews the imported records against the source export, spot-checking field mappings and verifying that Person-Company lookups resolved correctly. Any mapping corrections are applied before the production migration begins. We do not proceed to production until the dry-run reconciliation report shows record counts within an acceptable variance and the admin has signed off.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Companies first (no dependencies), then Persons (with company-name lookup resolved), then Opportunities (with Person and company references resolved), then Tasks (with assignee resolved against the User mapping), then Activities (reconstructed as Tasks and Notes linked to the correct Person or Company). Each phase emits a row-count reconciliation report before the next phase begins. During the production migration window, Rainbow CRM is placed in read-only mode to prevent new records from being created that would miss the migration cutover.

  6. Cutover, validation, and automation handoff

    We freeze Rainbow CRM writes during cutover, run a final delta migration of any records modified during the production migration window, then confirm Twenty as the system of record. We validate record counts, spot-check 25 random records against the source export, and deliver the written inventory of Rainbow CRM workflows and automations that require manual rebuild in Twenty's workflow builder. We provide a one-week hypercare window where we resolve any data issues raised by the customer's team. We do not rebuild Rainbow CRM automations as Twenty workflows inside the migration scope; that is a separate engagement or an internal admin task.

Most migrations land between three and five weeks for accounts under 10,000 Persons, 2,000 Opportunities, and no custom objects. Migrations with custom objects, large activity histories (over 100,000 denormalized activity rows), or multiple export files requiring merge-by-email deduplication move to six to ten weeks because of the custom field pre-creation step, the activity thread reconstruction pass, and the dry-run reconciliation cycle before production cutover.
