Overview
Knock CRM is purpose-built for multifamily leasing teams, with objects and workflows oriented around property tours, rental applications, lease tracking, and lead attribution across marketing channels. Its data model includes Contacts, Companies, Deals (as lease opportunities), Tasks, Notes, and custom fields for property-specific attributes like unit numbers, lease start dates, and application status. Twenty CRM is a general-purpose open-source CRM with standard People, Companies, Opportunities, Notes, and Tasks objects, plus an unrestricted custom object and custom field layer that can model any domain. FlitStack AI migrates every standard Knock object into its Twenty equivalent, maps custom leasing fields to Twenty custom fields (created via Settings → Data Model before import), and preserves original timestamps, owner email links, and association chains. Knock workflows, sequencing rules, and attribution automations do not migrate — we export your Knock workflow definitions as a rebuild reference for Twenty's workflow builder. Migration runs via Twenty's CSV import or REST/GraphQL API, with a 24–48 hour delta-pickup window capturing any records modified during cutover. A sample migration with field-level diff runs first so you verify the mapping before the full commit.
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 Knock 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.
Knock CRM
Contact
Twenty CRM
People
1:1Knock contacts map directly to Twenty People records. Email, phone, name, job title, and address fields carry over directly. The Knock contact owner resolves by email match to a Twenty Workspace Member. Knock contacts without a primary company land as standalone People records.
Knock CRM
Company / Property
Twenty CRM
Companies
1:1Knock companies (property listings) map to Twenty Companies. Property name, address, domain/website, industry classification, and unit count fields translate to their Twenty equivalents. Multi-property companies in Knock become multiple Company records in Twenty linked by a parent-company custom field. This ensures that each individual property location retains its own company identity in Twenty while maintaining the parent-child relationship through the custom field reference.
Knock CRM
Deal
Twenty CRM
Opportunities
1:1Knock deals representing lease opportunities map to Twenty Opportunities. Deal name, amount (rent or fee), stage, close date (lease start), and owner transfer directly. Knock's deal-stage values map to Twenty Opportunity Stage pick-list values per configured pipeline. Stage-enter timestamps from Knock are preserved as custom datetime fields on the Twenty Opportunity, maintaining your stage-transition history and allowing you to analyze pipeline velocity through the original timestamps.
Knock CRM
Pipeline Stage
Twenty CRM
Opportunity Stage
1:1Each Knock deal pipeline stage maps value-by-value to a Twenty Opportunity Stage within the same Opportunity. Knock stage-enter timestamps are preserved as custom datetime fields on the Opportunity for stage-history continuity. We surface stage-probability assumptions for your Twenty admin to configure.
Knock CRM
Task
Twenty CRM
Tasks
1:1Knock tasks map to Twenty Tasks with full assignment, due date, completion status, and parent-record links preserved. Tasks linked to Contacts, Companies, or Deals carry their Twenty equivalents as relation fields. Open versus completed status maps directly. Task priority levels migrate as a custom select field when present in Knock. Recurring task patterns are flagged for manual recreation in Twenty's task system.
Knock CRM
Note
Twenty CRM
Notes
1:1Knock notes migrate as Twenty Notes attached to the relevant People, Company, or Opportunity record. Original create timestamps and author information are preserved. Rich-text formatting in Knock notes converts to Twenty's note body format. Any embedded file references or links within notes are flagged as requiring post-migration verification.
Knock CRM
Custom Property (Contact)
Twenty CRM
Custom Field (People)
1:1Knock custom properties on contacts (e.g., application_status, leasing_agent, preferred_move_in_date) require pre-created custom fields in Twenty via Settings → Data Model before import. FlitStack generates a custom field creation plan based on your Knock property inventory. Text, date, select, and number field types map directly.
Knock CRM
Custom Property (Deal)
Twenty CRM
Custom Field (Opportunity)
1:1Knock deal custom fields (unit_number, lease_term_months, security_deposit, application_received_date) map to Twenty custom fields on Opportunities. These fields must exist in Twenty before the migration runs. We deliver a field creation checklist ordered by object so your admin pre-stages the schema.
Knock CRM
Owner / Team Member
Twenty CRM
Workspace Member
1:1Knock owner IDs resolve by email match to Twenty Workspace Members. Before migration, your Twenty workspace must have all active team members invited and accepted. Unmatched owners receive a fallback assignment or are flagged — no record lands without a valid Twenty owner.
Knock CRM
Association / Relationship
Twenty CRM
Relation Field
1:1Knock's contact-to-company and contact-to-deal associations map to Twenty relation fields (companyId on People, opportunityId on Opportunities). When a contact has multiple associated companies, the primary company maps as companyId and the rest surface as a custom relation note or are logged for manual re-linkage.
Knock CRM
Attachment / File
Twenty CRM
File Storage (External)
1:1Knock file attachments (lease documents, application PDFs, property images) are exported to local storage and re-uploaded to Twenty's file attachment field or external storage linked from the record. We flag any files exceeding Twenty's storage limits for manual handling. Files are organized by record type and linked to their corresponding People, Company, or Opportunity records to maintain the original attachment context.
Knock CRM
Workflow / Automation
Twenty CRM
N/A — manual rebuild
1:1Knock leasing sequences, task triggers, and attribution automations do not migrate. We export your Knock workflow definitions as a JSON/CSV rebuild reference so your Twenty admin can recreate logic in Twenty's workflow builder. Scheduling triggers and sequence steps require manual reconfiguration.

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.
Knock CRM gotchas
Prospect-to-Unit linkage is not a foreign key in all exports
Attribution data is a Prospect property, not a separate object
Pipeline stages are property-specific, not global
Lease records may lack full document blobs in standard export
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 Knock data and generate custom field creation plan for Twenty
FlitStack pulls a full export of your Knock objects — Contacts, Companies, Deals, Tasks, Notes, and all custom properties — and runs a field inventory. We identify every Knock custom property that has no native Twenty equivalent and generate a field creation plan listing each custom field's name, type (text, number, date, select), and select options if applicable. Your Twenty admin creates these fields at Settings → Data Model before we proceed. We validate field existence via Twenty's API before each import batch.
Invite all Knock owners to Twenty and resolve Workspace Members by email
Knock owner IDs map to Twenty Workspace Members via email. We scan your Knock owner list and cross-reference it against your Twenty Members list. Any owner without a matching invited member gets flagged — you either invite them to Twenty first or designate a fallback owner. This step gates the migration: no record lands with an unresolved owner assignment. Our pre-scan identifies all Knock team members who need workspace invitations before the migration begins, ensuring every owner can be properly assigned in Twenty without leaving records orphaned or unassigned.
Sequence migration in strict Twenty import order: Companies → People → Opportunities → Tasks → Notes
Twenty enforces referential integrity during CSV import, so we load Companies first, capture their new Twenty IDs, inject those IDs into the People CSV as companyId lookups, load People, capture their IDs, inject into Opportunities, and so on. We batch each object group separately (typically 5,000–10,000 records per batch) to stay within Twenty's API rate limits and keep rollback scope manageable. Each batch is independently auditable.
Run sample migration with field-level diff before full commit
A representative slice — usually 200–500 records spanning each object type — migrates first. We generate a field-level comparison showing source value versus destination value for every mapped field, highlighting any transformation discrepancies. You verify custom field mapping, owner resolution, stage value mapping, and association chain integrity before we proceed to the full run. Sample migration runs in 2–4 hours; you review the diff while the full migration queue builds.
Execute full migration with delta-pickup window and rollback on demand
Full migration runs against Twenty's API with batched commits. A delta-pickup window (24–48 hours after the last batch) captures any Knock records created or modified during cutover. FlitStack's audit log records every operation — insert, update, skip, quarantine — with source record IDs. If reconciliation reveals a mapping error or data integrity issue, one-click rollback reverts all Twenty changes to the pre-migration state. Post-migration, we deliver a reconciliation report showing record counts, quarantine batches, and unmapped field warnings.
