Overview

What this migration involves

Data Team DDS setups carry contacts, companies, deals, activities, and custom fields into Twenty CRM, which uses a flatter object model built around People, Companies, Opportunities, Tasks, and Notes. The migration maps People to Twenty's People object, Companies directly, and Opportunities to Twenty's Opportunities with stage and amount intact. Custom fields require pre-creation in Twenty Settings before data lands; FlitStack audits the source schema and lists every missing field so your admin can create them in the Data Model section. Activities (calls, emails, meetings) become Tasks and Notes in Twenty, preserving the original date, owner, and notes text, while thread relationships are flattened into discrete rows. FlitStack AI sequences the migration so foreign keys resolve correctly — Companies first, then People with their CompanyId, then Opportunities with their linked People, and finally Tasks and Notes linked to the appropriate People, Company, or Opportunity records. Owner assignments are resolved by email match to Twenty WorkspaceMembers, and any owners without a matching workspace account are flagged for admin invitation before the final import window. Workflows, automations, and sequence logic do not migrate and must be rebuilt in Twenty's workflow builder. The migration uses scoped read access on the source system; your team keeps working in Data Team DDS during cutover while FlitStack captures a final delta window before switching over, ensuring no record changes are missed.

Data Team DDS

What's pushing teams away

  • Practices report that limited integrations with imaging systems and lab partners force manual workarounds that erode efficiency gains
  • Custom reporting capabilities are often described as insufficient for practices tracking production by provider or case type
  • Smaller practices cite pricing as a barrier when evaluating tier upgrades for multi-location or multi-doctor setups
  • User interface complexity for staff with limited technical experience creates onboarding friction, especially for front-desk teams new to the system

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 Data Team DDS objects map to Twenty CRM

Each row shows how a Data Team DDS 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.

Data Team DDS

Contact / Person

maps to

Twenty CRM

People

1:1
Fully supported

Direct map. Twenty's People object stores individuals with name, email, phone, job title, and a relation to Companies. If Data Team DDS stores contacts without a linked company, they land in Twenty as standalone People records. All standard fields map directly; custom contact properties must be pre-created in Twenty Settings before import.

Data Team DDS

Company / Account

maps to

Twenty CRM

Companies

1:1
Fully supported

Direct map. Data Team DDS company records map to Twenty's Companies object. Parent-company hierarchies in Data Team DDS map to the ParentId relation in Twenty's Companies if that structure exists in the source export. Industry and employee count fields migrate as custom selects or numbers if they are present in the source data.

Data Team DDS

Deal / Opportunity

maps to

Twenty CRM

Opportunities

1:1
Fully supported

Direct map. Twenty's Opportunities object tracks deal name, amount, stage, close date, and linked company and people. Each Opportunity is a single deal row — Data Team DDS deal rows with line items become one Opportunity with the total amount unless your plan calls for splitting.

Data Team DDS

Pipeline / Deal Stage

maps to

Twenty CRM

Opportunities.stage

1:1
Fully supported

Data Team DDS pipeline stage names map to Twenty's Opportunity stage pick-list values. Stage probability percentages map as-is if the source exposes them, or are set as a custom field on Opportunities. Stage order is preserved for kanban view sequencing.

Data Team DDS

Activity (Call)

maps to

Twenty CRM

Task

1:1
Fully supported

Data Team DDS call logs migrate as Twenty Tasks with Type='Call' in the subject or a custom type field. Original call date, duration (if stored), owner, and notes are preserved. The Task is linked back to the People record via Twenty's relation field.

Data Team DDS

Activity (Email)

maps to

Twenty CRM

Task

1:1
Fully supported

Email engagement records map to Twenty Tasks with Type='Email'. Subject line, body content, sent/received timestamp, and owner are migrated. Thread linkage is flattened — individual emails become separate Task records rather than a threaded conversation view. If the source email includes attachments, the file references are preserved as URL attachments on the Task or re-uploaded to Twenty's file storage.

Data Team DDS

Activity (Meeting / Calendar)

maps to

Twenty CRM

Task

1:1
Fully supported

Meeting records from Data Team DDS map to Twenty Tasks with the meeting title as subject, start/end times as task date fields, and the invitee list as a comma-separated custom field or as linked People records if the meeting-object schema supports it.

Data Team DDS

Note / Free-text Note

maps to

Twenty CRM

Notes

1:1
Fully supported

Notes migrate as Twenty Notes attached to People, Companies, or Opportunities by their record ID. Rich-text formatting is preserved where Data Team DDS supports it; plain-text notes map without transformation. Each note's creation date and owner are stored as custom datetime and assignee fields to preserve audit trails.

Data Team DDS

Task / To-do

maps to

Twenty CRM

Tasks

1:1
Fully supported

Data Team DDS tasks and to-dos migrate directly to Twenty's Tasks object. Due date, assignee (resolved by email match to Twenty workspace members), status (open/closed), and subject are all carried over. Any custom task fields (e.g., priority, category) must be pre-created in Twenty Settings before migration, and are imported as custom fields on the Tasks object.

Data Team DDS

User / Owner

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

Data Team DDS owner and user IDs are resolved by email against Twenty workspace members. Users who exist in both systems map by email match. Users present only in Data Team DDS are flagged for your team to either invite to Twenty or assign to a fallback member before migration.

Data Team DDS

Custom Field (contact-level)

maps to

Twenty CRM

People custom field

1:1
Fully supported

Data Team DDS custom contact properties migrate as Twenty People custom fields. These must be pre-created in Twenty Settings Data Model before migration runs — the CSV import does not auto-create fields. Text, number, date, and select field types are supported natively.

Data Team DDS

Custom Field (company-level)

maps to

Twenty CRM

Companies custom field

1:1
Fully supported

Data Team DDS custom company properties become Twenty Companies custom fields. Same constraint as People custom fields — create them in Settings before importing data. Industry and employee count may already exist as standard Twenty fields depending on your version.

Data Team DDS

Custom Object

maps to

Twenty CRM

Custom Object

1:1
Fully supported

Data Team DDS custom objects map 1:1 to Twenty custom objects. Custom-object-to-standard-object relationships that use N:N associations in Data Team DDS may need junction objects in Twenty — this is surfaced in the migration plan before execution. All fields within custom objects are migrated as their respective types, and any missing field definitions are flagged for creation in Twenty Settings prior to the import run.

Data Team DDS

Attachment / File

maps to

Twenty CRM

Files (URL reference or re-upload)

1:1
Fully supported

File attachments linked to Data Team DDS records are preserved as URL references where the source exposes them. If Data Team DDS stores files internally, FlitStack downloads and re-uploads them to Twenty's file storage. Inline images in notes are extracted and re-hosted.

Data Team DDS

Workflow / Automation

maps to

Twenty CRM

Workflow Builder

1:1
Fully supported

Data Team DDS workflows, automations, and sequences do not migrate to Twenty. Twenty's workflow builder supports basic field-update and notification automations. FlitStack exports your Data Team DDS workflow definitions as a rebuild reference document for your Twenty admin. Your admin can use this export to recreate each workflow step manually in Twenty's builder, or leverage the v2.0 SDK to implement custom automation logic programmatically.

Pair-specific challenges

  • Twenty's CSV export cap requires batch planning for large datasets

    Twenty's built-in CSV export is limited to 20,000 records per export operation. Data Team DDS setups with more than 20,000 total records across People, Companies, Opportunities, and activities require FlitStack to pull in batches by object type using the API, then reassemble the export before loading. This adds planning time for large-volume migrations and is a hard constraint baked into Twenty's current UI export tool — it cannot be overridden without API-level batching.

  • Custom fields must be created in Twenty Settings before data lands

    Twenty's CSV import creates records but does not create fields — if a Data Team DDS custom property has no matching Twenty field, the import skips that column silently. FlitStack's pre-migration audit identifies every Data Team DDS custom property that lacks a Twenty counterpart, and your admin creates those fields in Settings Data Model before the migration run commits. This is a sequencing constraint: field creation precedes data import, not the other way around.

  • Workflows, automations, and sequences do not migrate

    Data Team DDS automation logic — workflow rules, triggers, sequence steps, and notification routing — is platform-native and cannot be extracted in a form that Twenty's workflow builder can consume directly. FlitStack exports your workflow definitions as a structured reference document so your Twenty admin can rebuild each automation in Twenty's workflow builder. This manual rebuild step is a project-level effort that should be scoped separately from the data migration timeline.

  • Activity history flattened to Tasks — no threaded conversation view

    Twenty Tasks represent individual activities (a call, an email, a meeting) as separate records linked to People or Opportunities. Data Team DDS may store these as threaded conversations or associated activity logs. Migrated activities land as discrete Task rows in Twenty — thread continuity is lost in the sense that there is no parent-child relationship between emails in the same thread. Notes attached to People or Opportunities preserve full text but do not inherit a conversation structure.

  • Twenty lacks native lead-score and grading fields

    Data Team DDS setups that use built-in lead scoring, contact grading, or engagement scoring will not find equivalent native fields in Twenty's standard People object. These values migrate as custom number fields on People, created before migration as outlined in the custom field requirement above. Scoring logic that automated actions based on score thresholds in Data Team DDS must be rebuilt as workflow rules in Twenty's builder. If the built-in workflow builder does not meet your scoring needs, you can extend functionality with custom code using Twenty's v2.0 SDK, which allows you to define additional fields and automation triggers programmatically.

Migration approach

Six steps for a successful Data Team DDS to Twenty CRM data migration

  1. Discover Data Team DDS schema and target Twenty workspace

    FlitStack audits your Data Team DDS environment: enumerates all objects (People, Companies, Opportunities, custom objects), lists every standard and custom field per object, samples data quality metrics, and checks owner/user email coverage. In parallel, we review your target Twenty workspace — confirming which standard fields exist, what custom fields are already created, and verifying that all workspace members with email addresses are invited. This produces a field-mapping document and a Twenty pre-flight checklist before a single record moves.

  2. Create Twenty custom fields and invite workspace members

    Your Twenty admin (or FlitStack on your behalf) creates any missing custom fields identified in the audit — People, Companies, and Opportunities custom fields that lack a standard Twenty equivalent. All team members who appear as record owners in Data Team DDS must be invited to the Twenty workspace and accept their invitations before migration runs, because Twenty resolves owner assignments by email match and fails to link records when a user does not yet exist in the workspace.

  3. Run a sample migration with field-level diff

    A representative slice of records — typically 200–500 spanning People, Companies, Opportunities, and a handful of activity records — migrates into Twenty first. FlitStack generates a field-level diff comparing each source field value against the corresponding Twenty field value so you can verify that custom field mappings, stage name translations, owner resolution, and date handling all produce the expected result. You approve the sample before the full migration commits.

  4. Execute full migration with scoped read access and delta-pickup

    The full data migration runs against Twenty using CSV import (for record volumes under 20,000 per object) or API batch operations (for larger volumes requiring the 20,000-record export workaround). Your Data Team DDS account continues to operate normally — FlitStack holds scoped read access only. A delta-pickup window captures any records created or modified in Data Team DDS during the cutover. An audit log records every operation, and one-click rollback is available if reconciliation identifies a mapping error before you confirm the migration as complete.

Source

Strengths

  • Specialized for dental practice workflows including scheduling, treatment planning, and insurance claim handling
  • Patient record management consolidates demographics, clinical history, and billing in one linked system
  • Appointment scheduling with provider assignment supports multi-chair and multi-provider practice configurations
  • Insurance claim tracking with payer reference and status monitoring reduces follow-up effort on rejected claims
  • Custom fields allow per-practice configuration for referral tracking, recall preferences, and specialty flags

Weaknesses

  • Reporting and analytics capabilities lag behind broader CRM platforms, limiting production and revenue-cycle insights
  • Integration ecosystem is narrower than horizontal CRMs, requiring custom work for specialty imaging, lab, or ERP connections
  • Custom field schema varies by practice, creating migration complexity when switching to a destination system with a different data model
  • Multi-location support is limited on lower tiers, restricting scalability for growing dental groups
  • Export mechanisms may require manual intervention or third-party tools, as no fully documented public API was found in the research

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.

For datasets under 50,000 total records (People, Companies, Opportunities, and activities), the migration typically completes in 48–72 hours of clock time after your Twenty workspace is pre-configured and the sample migration is approved. Sets above 50,000 records or those with multiple custom objects extend to 7–14 days, primarily due to the 20,000-record CSV export cap in Twenty requiring API-level batching. The longest single step is usually creating custom fields in Twenty and getting owner email matches resolved before the import begins.
