Overview

What this migration involves

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.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Why teams make this switch

Two sides of the same decision

Leaving

Knock CRM

What's pushing teams away

  • Feature limitations in non-enterprise tiers frustrate teams that need advanced customization or debugging tools once they scale beyond initial setup.
  • Difficult setup and complex environment management create friction for teams expecting a straightforward onboarding, particularly around UI reliance.
  • Notification issues and UI update confusion cause teams to lose track of prospect follow-ups at critical moments in the leasing pipeline.
  • Some customers find the platform missing capabilities they expected after evaluating alternatives like AppFolio or ResMan.

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 Knock CRM objects map to Twenty CRM

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

maps to

Twenty CRM

People

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Companies

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Opportunities

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Opportunity Stage

1:1
Fully supported

Each 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

maps to

Twenty CRM

Tasks

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Notes

1:1
Fully supported

Knock 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)

maps to

Twenty CRM

Custom Field (People)

1:1
Fully supported

Knock 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)

maps to

Twenty CRM

Custom Field (Opportunity)

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Workspace Member

1:1
Fully supported

Knock 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

maps to

Twenty CRM

Relation Field

1:1
Fully supported

Knock'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

maps to

Twenty CRM

File Storage (External)

1:1
Fully supported

Knock 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

maps to

Twenty CRM

N/A — manual rebuild

1:1
Fully supported

Knock 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.

Pair-specific challenges

  • Custom fields must be pre-created in Twenty before migration commits

    Twenty's CSV import creates records, not fields — if a Knock custom property has no matching Twenty field, its data drops silently during import. FlitStack generates a custom field creation checklist (field name, type, select options) ordered by object so your Twenty admin pre-stages the schema. Fields must exist at Settings → Data Model before the migration runs. We validate field existence against Twenty's API before each batch commits, but the creation step itself is a manual admin action in Twenty.

  • Import order is strictly enforced in Twenty — companies before people before opportunities

    Twenty's CSV import requires referential integrity: the 'one' side of a relationship must exist before the 'many' side. This means Companies load first (so People can reference companyId), then People (so Opportunities can reference the right contact records), then Opportunities, then Tasks and Notes last. Knock's export sequence may not match this order. FlitStack sequences the migration batches in the correct order, extracts foreign key IDs from each batch output, and injects them into the next batch's CSV. If your Knock data has circular or missing company references, we flag those records for resolution before the People batch runs.

  • Knock leasing workflows and attribution sequences do not migrate — they require manual rebuild

    Knock's automation engine drives leasing sequences, task triggers based on pipeline stage changes, and marketing channel attribution. Twenty has its own workflow builder, but the logic is entirely separate and must be reconstructed from scratch. We export your Knock workflow definitions as a JSON reference file covering sequence steps, trigger conditions, and wait intervals so your Twenty admin can map each step to Twenty's workflow actions. The rebuilding effort is proportional to the number of Knock workflows and the complexity of stage-based triggers — typically 1–3 days of admin work for a typical 10-workflow Knock setup.

  • Knock owner IDs require matched Twenty Workspace Members before migration

    Every Knock owner is an email-addressed team member, but Twenty tracks assignees as Workspace Members. If a Knock owner record references an email with no corresponding invited Workspace Member in Twenty, that record's owner field lands empty. We run an email matching scan against your Twenty Members list before migration, flag unmatched owners, and give you the option to invite them to Twenty first or assign a fallback owner. Records without any valid owner assignment are held in a quarantine batch until resolved.

  • Multi-company contact associations collapse to a single companyId

    Knock allows a contact to be associated with multiple companies simultaneously (a leasing agent linked to multiple property management companies). Twenty People records have a single companyId lookup. FlitStack migrates the primary company association (most recently modified by default, or by your specified rule) as the companyId, and preserves secondary company associations as a JSON array in a Secondary_Companies__c custom field for manual re-linkage. If you need full N-to-N resolution in Twenty, that requires a custom junction object which your admin configures post-migration.

Migration approach

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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Source

Strengths

  • Purpose-built for multifamily — every feature maps to the renter lifecycle from tour to lease to renewal.
  • Self-scheduling via Knock Now increases tour volume without adding marketing headcount.
  • Marketing attribution across email, text, voice, and chat is centralized in one screen per prospect.
  • Automated reporting reduces manual data compilation for regional and portfolio managers.
  • Strong customer support responsiveness and fast bug resolution compared to larger competitors.

Weaknesses

  • Limited to multifamily — not usable for commercial, retail, or non-real-estate CRM use cases.
  • Feature gaps in non-enterprise tiers leave growing teams without advanced customization or debugging tools.
  • Setup complexity and environment management create friction for teams expecting a quick start.
  • Notification reliability issues occasionally cause prospect follow-ups to be missed.
  • Craigslist posting tool and other niche leasing features lack robustness compared to dedicated tools.

Destination

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.

Most Knock-to-Twenty migrations complete in 24–48 hours of execution time for under 25,000 records. The pre-migration phase — custom field creation in Twenty, owner resolution, and data audit — typically takes 2–5 business days depending on your Knock data complexity. Configurations with heavy custom leasing fields, multi-pipeline deal structures, or records exceeding 250,000 extend to 5–7 days. Twenty's strict import order (Companies → People → Opportunities) is the primary sequencing constraint.
