Overview
Moving from CRUMP CRM to Twenty CRM means leaving a Dynamics 365-licensed all-in-one suite for an open-source, self-hostable CRM that prioritises developer flexibility and transparent data ownership. CRUMP CRM has no public REST API reference; we access the underlying Dynamics 365 instance directly, which requires admin credentials with sufficient read privileges and is gated by your current Dynamics 365 licence tier. Twenty has no built-in import UI as of 2026 — we use its GraphQL API or a CSV ingestion script with fields pre-created in Settings before any record import. We migrate Contacts, Companies, Opportunities, Tasks, Notes, Tickets, and any enumerated Custom Objects, but not Attachments, Workflows, Automations, or reporting configurations, which require rebuild in Twenty or external tooling post-migration.
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 CRUMP 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.
CRUMP CRM
Contact
Twenty CRM
People
1:1CRUMP CRM Contacts correspond directly to Twenty People. We export from the Dynamics 365 Contact entity, map standard fields (full name, email, phone, address) to Twenty's People object fields, and resolve the Owner lookup to a pre-invited Twenty Member by email match. Custom properties on Dynamics 365 Contacts require enumeration during audit and pre-creation in Twenty Settings before import.
CRUMP CRM
Account
Twenty CRM
Company
1:1CRUMP CRM Accounts map 1:1 to Twenty Companies. The account name becomes the Company name, and domain information maps to the website field. Parent-child account hierarchies in Dynamics 365 are preserved as Company relations in Twenty. We create the Company before any People import so that the relationship lookup is satisfied at insert time.
CRUMP CRM
Deal
Twenty CRM
Opportunity
1:1CRUMP CRM Deals correspond to Opportunities in Twenty. Deal value, close date, pipeline stage, and owner migrate directly. Stage names from Dynamics 365 are mapped to Twenty Opportunity stage values; if the destination pipeline does not yet exist we create it in Settings before migration. Closed-Won and Closed-Lost reasons migrate as custom Opportunity fields.
CRUMP CRM
Project
Twenty CRM
Custom Object (Project)
1:1CRUMP CRM's Project Management module stores Projects as a distinct Dynamics 365 entity. We export Project records (name, status, start/end dates, assigned team members) and create a matching Custom Object in Twenty called Project. Task-level detail from the project module may be partial depending on Dynamics 365 licence tier; we document any truncated fields in the migration inventory.
CRUMP CRM
Ticket (Case)
Twenty CRM
Custom Object (Ticket) or Note
1:1Helpdesk tickets in CRUMP CRM are Cases in Dynamics 365 terminology. We export ticket status, priority, description, and linked contact. If the destination team uses Twenty's task model for support tracking we map to Tasks with a custom Ticket label field; otherwise we create a Ticket custom object and link it to the originating People record.
CRUMP CRM
Invoice
Twenty CRM
Custom Object (Invoice)
1:1CRUMP CRM's bundled invoicing module stores Invoice records with line items, totals, and payment status. We export invoice data and create a matching Invoice custom object in Twenty. The relationship to the originating Deal or Project must be reconstructed from the export since Dynamics 365 may store these links in separate tables. We document the reconstructed relationship in the migration inventory.
CRUMP CRM
Task
Twenty CRM
Task
1:1Tasks exist across multiple CRUMP CRM modules (CRM tasks, project tasks, helpdesk tasks). We deduplicate and label each task by its origin module using a custom source_module field. Task status, priority, due date, and assignee migrate directly. HubSpot-style engagement notes are mapped to Twenty Notes linked to the parent record.
CRUMP CRM
User (Team Member)
Twenty CRM
Member
1:1CRUMP CRM user accounts and role assignments require explicit mapping to Twenty Members. We resolve by email match. Inactive users in CRUMP CRM are archived rather than imported to avoid ghost records. The customer's admin must invite all active users to Twenty before the migration begins, per Twenty's documentation requirement that referenced users exist before Owner lookups can resolve.
CRUMP CRM
Custom Object (Dynamics 365 custom entity)
Twenty CRM
Custom Object
1:1Any custom entities created on top of Dynamics 365 are enumerated during the audit phase. Each custom entity and its fields are documented and mapped individually. We pre-create the matching custom object in Twenty Settings before import, including all custom fields and relationship fields, because Twenty requires fields to exist before CSV import can create records.
CRUMP CRM
Note
Twenty CRM
Note
1:1CRUMP CRM notes migrate to Twenty Notes linked via the relation system to the parent People, Company, or Opportunity record. Note body preserves rich text where supported. If the note has attachments these are flagged as a separate file-level pass since binary blob migration through the API layer requires additional handling.

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.
CRUMP CRM gotchas
Dynamics 365 licensing tier gates API access
No publicly documented API endpoint or developer portal
Per-user pricing creates predictable but escalating costs
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
Discovery and Dynamics 365 licence audit
We audit the CRUMP CRM instance by enumerating the entities exposed by the underlying Dynamics 365 instance. We identify active modules (CRM, Helpdesk, Project Management, Invoicing), count record volumes per object type, and confirm the Dynamics 365 licence tier assigned to the source org. This determines which entities are API-accessible and flags any that require a licence upgrade before export. We also extract a full list of custom entities and their field definitions for custom object mapping. The discovery output is a written migration scope and a list of any pre-requisite actions (such as licence upgrade or partner-level access provisioning).
Schema design and Twenty workspace preparation
We design the destination schema in Twenty before any data import. This means creating all required objects (Companies, People, Opportunities, Tasks, Notes, and any custom objects), then creating all fields on each object, then configuring select options, required settings, and relation fields. This step is necessary because Twenty ignores CSV columns for fields that do not yet exist. We also invite all active team members as Members so that Owner lookups can resolve during import. The customer's admin reviews and approves the schema before we proceed.
User reconciliation and Member provisioning
We extract every distinct CRUMP CRM user referenced on Contact, Account, Deal, Project, Ticket, and Task records and match by email against the Twenty Members list. Users without a matching Member are held in a reconciliation queue. The customer's admin provisions any missing Members in Twenty before record import resumes, because OwnerId references on Opportunities and Tasks cannot resolve without a corresponding Member record in the destination.
Data export from Dynamics 365
We export data from the Dynamics 365 instance using the appropriate API (web API or OData) with batch chunking and exponential backoff on rate-limit responses. Exports run in dependency order: Accounts first, then Contacts (with AccountId resolved), then Opportunities, then Tasks and Notes, then Custom Objects. Projects and Tickets export last. We flag any entity that falls outside the Dynamics 365 licence scope and escalate before the export phase begins. Each export emits a row-count reconciliation report.
Transform, load, and relationship resolution
We transform exported records into Twenty-compatible CSV format or GraphQL API payloads. Relationship lookups (People to Company, Opportunity to Company, Task to People) are resolved using the pre-built mapping. Field type transformations handle date formats, phone number normalisation, and picklist value mapping. We run the load in dependency order: Companies first, then People, then Opportunities, then Tasks and Notes, then Custom Objects. Each phase emits a load report with success, warning, and error counts before the next phase begins.
Validation, cutover, and workflow inventory delivery
We run a reconciliation pass comparing row counts in Twenty against the source export totals, spot-check 25-50 records for field-level accuracy, and validate relationship integrity (People linked to correct Companies, Opportunities linked to correct People and Companies). We deliver a written inventory of every CRUMP CRM workflow, automation, and form with a description of what it does and a recommendation for how to reproduce it in Twenty or external tooling. We do not rebuild automations as part of the migration scope. We support a one-week post-cutover window for reconciliation issues raised during live use.
