Overview
Constructor CRM stores contacts, companies, and deals in a standard relational model with owner assignments and custom field support. Twenty CRM exposes these as People, Companies, and Opportunities objects built on a TypeScript/NestJS backend with a PostgreSQL database and a GraphQL API. FlitStack AI sequences the migration to respect Twenty's import-order constraint: Companies first (the 'one' side of relationships), then People (linked via companyId), then Opportunities (linked to both), and custom objects last. We preserve original create dates as custom fields since Twenty sets CreatedAt at import time. Owner resolution happens by email match against Twenty workspace members — your team must exist in Twenty before records referencing them can link correctly. Constructor workflows, automation rules, and sequence configurations do not migrate; we export them as JSON重建 references for your Twenty admin. Attachments export from Constructor and re-upload to Twenty's file storage. Delta-pickup captures any records modified during the cutover window.
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 Constructor 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.
Constructor
Contact / Person
Twenty CRM
People
1:1Constructor contacts migrate as Twenty People records. First name, last name, email, phone, job title, and address fields map directly. The People object links to Companies via the companyId field — Constructor contacts without a primary company receive a 'Unassigned' placeholder or remain standalone until a company link is established during the Companies import phase.
Constructor
Account / Organization
Twenty CRM
Companies
1:1Constructor accounts map to Twenty Companies. The Companies object in Twenty stores displayName, domain (website), industry, size, and location fields. Constructor parent-child account hierarchies translate to Twenty's company-to-company relationships via a parentCompanyId field if your Constructor setup uses organizational hierarchies.
Constructor
Deal / Opportunity
Twenty CRM
Opportunities
1:1Constructor deals migrate as Twenty Opportunities with the same deal name, amount, stage, and expected close date. Twenty Opportunities link to Companies (accountId) and can link to People (point of contact). Stage names map value-by-value if Constructor uses a pick-list for stages — we preserve the original stage labels as Opportunity stage values in Twenty.
Constructor
Note / Annotation
Twenty CRM
Notes
1:1Constructor notes attach to contacts, companies, or deals. In Twenty, Notes are standalone objects that link to People, Companies, Opportunities, or other records via the NoteTargets relation. We preserve the original note body, author, and create timestamp. Rich-text formatting converts to Twenty's supported note format.
Constructor
Task / To-Do
Twenty CRM
Tasks
1:1Constructor tasks migrate as Twenty Tasks with the task title, due date, assignee, completion status, and body preserved. Tasks link to the parent record (People, Company, or Opportunity) via taskId. Completed versus open status carries over as a boolean completed field in Twenty.
Constructor
Activity / Engagement (Call, Email, Meeting)
Twenty CRM
Tasks / Events
1:1Constructor activity logs (call logs, email threads, meeting records) split based on type. Call and email activities become Tasks with Type='Call' or Type='Email' in Twenty. Meeting records with start/end times convert to Twenty Tasks with a scheduled datetime if Twenty's event model is not available in your version. Original activity timestamps and owners (resolved by email) are preserved.
Constructor
Custom Object
Twenty CRM
Custom Object
1:1Constructor custom objects migrate 1:1 to Twenty custom objects. Your Twenty workspace must have the custom object schema created (via Settings → Data Model → Create new object) before migration runs. We export the custom object definition from Constructor and use Twenty's Metadata API to create matching objects with the same field types — text, number, date, select, multi-select, or relation.
Constructor
Custom Field (on standard objects)
Twenty CRM
Custom Field (on People, Companies, Opportunities)
1:1Constructor custom fields on contacts, accounts, or deals require pre-creation in Twenty's data model before CSV import. We document all custom fields in the mapping plan, flag which Twenty object each custom field belongs to, and include the field type from Constructor. Your admin creates these in Settings → Data Model first — FlitStack cannot create fields, only data.
Constructor
User / Owner
Twenty CRM
WorkspaceMember
1:1Constructor users and deal owners resolve by email match against Twenty workspace members. The Twenty import documentation explicitly requires that users exist before importing records that reference them — we flag unmatched owners before migration and either invite them to Twenty first or assign their records to a fallback workspace member.
Constructor
Attachment / File
Twenty CRM
File
1:1Constructor file attachments on contacts, companies, or deals export from Constructor's storage and re-upload to Twenty's file storage. We preserve the original file name, mime type, and upload timestamp. Files attach to the parent record in Twenty using the file associations API. Size limits from Constructor's export apply.
Constructor
Workflow / Automation
Twenty CRM
Workflow (Twenty)
1:1Constructor workflows and automation rules do not migrate to Twenty. Twenty's workflow builder operates differently from Constructor's automation engine. We export your Constructor workflow definitions as a JSON reference file so your Twenty admin can rebuild them in Settings → Workflows. This is a manual step that requires process review.
Constructor
Sequence / Cadence
Twenty CRM
N/A
1:1Constructor sequences and outreach cadences do not transfer. Reddit discussions about Twenty note that it 'lacks native sequencing' as of v1.0. Sequences must be rebuilt manually in Twenty or via a third-party sales engagement tool. We export sequence definitions as reference documentation.

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.
Constructor gotchas
Reporting and filter limitations make pre-migration data inventory harder
Estimating templates and take-offs carry business logic, not just data
KeyPay payroll data lives in a connected but separate system
Uptime variability requires staged migration windows
Custom integrations (Salesforce, ClickHomes, OCR, ELO) need separate scoping
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
Audit Constructor data model and export all objects
We connect to Constructor via API or CSV export to inventory all objects: People, Companies, Opportunities, Notes, Tasks, custom objects, and attachments. We document field types, pick-list values, relationship cardinalities, and owner distribution. This audit identifies data quality issues (duplicate emails, missing required fields), custom field counts, and any non-standard objects that need custom object creation in Twenty before migration. The output is a detailed data map and a cleanup checklist delivered before any migration work begins.
Create Twenty schema — custom fields and custom objects first
Your Twenty admin (or our team with admin credentials) creates all custom fields in Settings → Data Model before we touch any data. We deliver a field creation checklist mapped from the Constructor audit: object name, field label, field type, and pick-list options for select fields. Custom objects get created with their schema via Twenty's Metadata API. We verify all fields exist in Twenty before proceeding to export — Twenty's import will reject CSV rows referencing fields that do not yet exist.
Resolve owners and invite users to Twenty workspace
We match Constructor owner email addresses against Twenty workspace members by email. Records with unmatched owners are listed with their Constructor owner name and email so you can decide: invite that person to Twenty first, or reassign their records to a fallback workspace member. This step gates the migration — no record with an unresolved workspaceMemberId reference can import cleanly. We require written confirmation that all owner references are resolved before the migration run commits.
Run sequenced migration — Companies, then People, then Opportunities
Following Twenty's import-order constraint, we migrate in three sequenced phases. First: Companies CSV with displayName, domain, industry, employees, annualRevenue, and parentCompanyId for hierarchy. Second: People CSV with firstName, lastName, email, phone, jobTitle, and companyId linking each contact to its parent Company. Third: Opportunities CSV with name, amount, stage, expectedCloseDate, probability, companyId, and personId for primary contact. Each phase validates row counts and relationship resolution before the next phase begins.
Run sample migration with field-level diff before full commit
A representative sample (typically 100–500 records spanning People, Companies, and Opportunities) migrates first into your Twenty workspace. We generate a field-level diff report comparing source Constructor values to the resulting Twenty fields, highlighting any truncation, format changes, or dropped values. You review the diff and confirm mapping accuracy before the full migration run commits. This prevents bulk data issues from reaching production in Twenty.
Execute full migration with delta-pickup window and rollback plan
Full migration runs against Twenty with a delta-pickup window (24–48 hours) capturing any records created or modified in Constructor during cutover. Audit logs record every operation. We provide a one-click rollback procedure if reconciliation fails — the pre-migration backup remains intact until you confirm the migrated data is accurate. Post-migration, we deliver a final reconciliation report comparing Constructor record counts to Twenty record counts per object, plus any records that failed import with error reasons for manual resolution.
