Overview

What this migration involves

Moving from ASPEC CRM to Twenty CRM is a migration from a compact, single-tenant platform with no documented API to an open-source CRM with a modern REST API and active GitHub community. The primary structural challenge is that ASPEC has no public API for automated data extraction, so we coordinate with the customer to extract data through the platform UI or direct database access before any migration work begins. ASPEC also separates custom field definitions from record data in a distinct metadata layer, which means we run a mandatory schema audit before writing to Twenty so that no per-user custom fields are silently dropped. We map ASPEC's pipeline stages directly to Twenty Opportunities but configure Twenty's pipeline stages and pipeline column layout in the destination first. Activities (calls, emails, tasks, meetings) migrate as Twenty Tasks with the correct linked entity resolved at import time. We do not migrate ASPEC Reports, Attachments, or automation workflows; we deliver a written handoff inventory for the customer's admin to rebuild these in Twenty's UI.

Why teams make this switch

Two sides of the same decision

Leaving

ASPEC

What's pushing teams away

  • Limited name recognition and company brand awareness compared to major CRM platforms
  • Small user base means fewer community resources, templates, and third-party integrations
  • Single verified review limits visibility into long-term reliability and support track record

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 ASPEC objects map to Twenty CRM

Each row shows how a ASPEC 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.

ASPEC

Contact

maps to

Twenty CRM

Person

1:1
Fully supported

ASPEC Contact records (name, email, phone, address, owner assignment) map directly to Twenty CRM's Person object. We extract every Contact field including per-user custom fields enumerated during schema discovery and write them as typed fields on the Person record. The email address serves as the dedupe key during import. ASPEC owner assignment maps to Twenty's workspaceMember field resolved via the User mapping step.

ASPEC

Company

maps to

Twenty CRM

Company

1:1
Fully supported

ASPEC Company records map directly to Twenty's Company object, preserving the link to associated Contacts and Opportunities. The domain from ASPEC's company data becomes the Website field in Twenty. We create Companies before Person records during import so that the company-to-person relationship is satisfied at Person insert time.

ASPEC

Opportunity

maps to

Twenty CRM

Opportunity

1:1
Fully supported

ASPEC Opportunity records (deal name, value, stage, expected close date) map to Twenty CRM Opportunity. The stage name from ASPEC maps directly to Twenty's stage field, but any custom ASPEC stage labels require value-mapping to Twenty's pipeline stage enum before import. ASPEC's pipeline association maps to Twenty's pipeline field, which we configure during the schema setup phase.

ASPEC

Pipeline Stage

maps to

Twenty CRM

Pipeline + Stage

lossy
Fully supported

ASPEC pipelines define stage names and ordering in a separate configuration layer. We capture the full pipeline configuration during the schema discovery step, then create matching Twenty CRM pipelines and stage definitions via the Twenty metadata API before Opportunities are imported. Stage probabilities migrate from ASPEC if available and are set on the corresponding Twenty stage record.

ASPEC

Activity: Call

maps to

Twenty CRM

Task (type = call)

1:1
Fully supported

ASPEC call activity records (timestamped, linked to Contact or Company) map to Twenty Task records with type = call. Call disposition and duration transfer to custom Task fields if defined in the Twenty schema during setup. Activity timeline ordering is preserved by setting the createdAt timestamp to the original ASPEC activity timestamp.

ASPEC

Activity: Email

maps to

Twenty CRM

Task (type = email)

1:1
Fully supported

ASPEC email activity records map to Twenty Task with type = email and the email body preserved in the Task description field. The linked Contact or Company from ASPEC resolves to the Twenty Person or Company record at migration time using the email address or record ID cross-reference.

ASPEC

Activity: Meeting

maps to

Twenty CRM

Task (type = meeting)

1:1
Fully supported

ASPEC meeting records map to Twenty Task with type = meeting, preserving location, start time, and end time. Attendees from ASPEC are recorded in the Task's linked-people field or as a custom multi-select field in Twenty, depending on the schema configuration decided during scoping.

ASPEC

Activity: Task

maps to

Twenty CRM

Task (type = task)

1:1
Fully supported

ASPEC task activity records (status, priority, due date, owner) map to Twenty Task records with type = task. Status and priority from ASPEC map to Twenty's status and priority enums. Task owner assignment resolves via the User mapping step using the ASPEC owner email as the match key.

ASPEC

Custom Fields

maps to

Twenty CRM

Custom Fields

lossy
Mapping required

ASPEC stores per-user custom field definitions in a separate metadata layer. We run a mandatory schema discovery step before any data migration, enumerating all active custom fields, their data types, and which objects they are attached to. We then pre-create the matching custom field definitions in Twenty CRM's schema via the /metadata API before record import begins. Skipping this step means custom fields are silently absent from migrated records.

ASPEC

Tag/Label

maps to

Twenty CRM

Custom Field (multi-select or Topic)

lossy
Fully supported

ASPEC tags on Contacts and Companies migrate as multi-select picklist fields in Twenty or as tagged-objects depending on the customer's preferred organization strategy. We capture all distinct tag values during schema discovery and configure the target field type during the schema setup phase. The customer chooses the tag strategy during scoping.

ASPEC

User/Owner

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

ASPEC record ownership assigns to Users, which we map to Twenty CRM workspaceMembers. We resolve ASPEC owners by email match against Twenty User records created during setup. Any ASPEC owner without a matching Twenty user is held in a reconciliation queue for the customer to provision before record import resumes. Archived or inactive ASPEC users require explicit reactivation decisions from the customer.

Pair-specific challenges

  • ASPEC has no documented public API

    ASPEC CRM does not appear to publish a public REST or bulk API for programmatic data extraction. This is the single largest technical constraint on the migration. We handle this by working directly with the customer's data export from the platform's UI (CSV downloads per object) or via database-level access if available on their hosting plan. We always run a scoping call to confirm the export method before migration begins. Manual exports introduce the risk of partial data if pagination across large record sets is not handled carefully, and there is no way to run delta migrations without re-exporting the entire dataset. Twenty CRM's documented REST API and /metadata route eliminate this constraint permanently after cutover.

  • Custom field schema lives outside the record data

    ASPEC separates custom field definitions from the Contact, Company, and Opportunity records. We run a mandatory schema discovery step before writing any data, enumerating all active custom fields, their data types, and the objects they attach to. We then pre-create matching custom field definitions in Twenty CRM's schema via the /metadata API before any record import. If this step is skipped, custom fields are silently absent from migrated records, and the customer discovers the gap only after the migration is complete. This gotcha is specific to ASPEC because the separation is structural rather than incidental.

  • Twenty lacks native reporting and dashboards on free tier

    Twenty CRM's free self-hosted tier does not include dashboards or chart visualizations. This gap is documented across multiple open-source CRM benchmarks (Marmelab 2025 and 2026). If the customer relies on ASPEC's basic reporting and dashboards, they should plan to use the Organization cloud tier ($9/user/mo) or integrate with an external BI tool post-migration. We flag this during scoping so that reporting dependencies are accounted for in the destination tier decision.

  • Twenty has no mobile app on self-hosted

    Twenty CRM does not have a native mobile application. For teams with field sales or remote reps who rely on ASPEC's mobile access, this is a functional gap that must be evaluated before migration. If mobile access is required, the customer should use Twenty's cloud tier, where a mobile app is included. We raise this as a checklist item during discovery so it does not become a post-migration surprise.

  • Workflows and automations do not migrate

    ASPEC workflow configurations, if any are in use, are not exposed via any documented API and do not have a structural equivalent in Twenty CRM. Twenty does not support legacy workflow automation in the same model as ASPEC. We do not migrate automations as code. We deliver a written inventory of any ASPEC workflow or automation configuration the customer identifies during scoping, with a recommended manual-rebuild approach for Twenty's UI-based pipeline automation features.

Migration approach

Six steps for a successful ASPEC to Twenty CRM data migration

  1. Discovery and export method confirmation

    We audit the ASPEC portal across active objects, custom field definitions, pipeline configurations, activity volumes, and any identified workflows or automations. Because ASPEC has no public API, we confirm the export method during this step: direct CSV export per object from the ASPEC UI, or database-level access if available on the customer's hosting plan. We also assess the target Twenty CRM tier (cloud vs self-hosted) and confirm whether SSO, mobile access, and reporting depth requirements influence the tier decision. The discovery output is a written migration scope document covering record counts, custom field inventory, and export method.

  2. Schema discovery and custom field enumeration

    We run the mandatory schema discovery step against the ASPEC export data, enumerating every active custom field, its data type, and which objects it is attached to. We cross-reference this with any schema metadata accessible through the customer's hosting environment. We then pre-create the matching custom field definitions in Twenty CRM's workspace via the /metadata API, configure pipeline structures matching the ASPEC pipeline configuration, and set up the stage enum values before any record data is written. This step runs before any data migration and prevents silent custom-field drops.

  3. Owner reconciliation and Twenty user provisioning

    We extract every distinct ASPEC Owner referenced on Contact, Company, Opportunity, and Activity records and match by email against the Twenty CRM destination workspace's user table. Owners without a matching Twenty user are held in a reconciliation queue. The customer provisions any missing users in Twenty before migration proceeds. This step must complete before record import because OwnerId references are required on most standard objects in Twenty.

  4. Sandbox migration and reconciliation

    We run a full migration into the customer's target Twenty environment using production-like data volume. For self-hosted deployments this means a staging instance; for cloud deployments it means the target workspace with a test dataset. The customer reconciles record counts (Persons, Companies, Opportunities, Tasks), spot-checks 25-50 records against the ASPEC source, and approves the schema and mapping before production migration begins. Any custom field mapping corrections, stage-label mismatches, or tag-strategy decisions happen here, not in production.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Companies (created first for relationship integrity), Persons (with AccountId resolved), Opportunities (with pipeline and stage resolved), Activity history (Tasks of all types with linked-entity resolution). Each phase emits a row-count reconciliation report before the next phase begins. For large activity histories we use Twenty's bulk import capability with chunking. Tags migrate after the base object migration completes, using the strategy agreed during scoping.

  6. Cutover, validation, and handoff inventory

    We freeze any live writes to ASPEC during the cutover window, run a final delta migration of any records modified during the migration window, then enable Twenty CRM as the system of record. We deliver a written handoff inventory covering any identified ASPEC workflows or automations (for manual rebuild in Twenty), a report of any records that could not be migrated due to missing dependencies, and the full custom field and pipeline configuration as-built documentation. We support a one-week hypercare window for reconciliation issues. We do not rebuild ASPEC automations, Reports, or Attachments as those fall outside the migration scope.

Most ASPEC to Twenty CRM migrations land between three and five weeks for accounts under 15,000 Contacts and 3,000 Opportunities with fewer than 50 custom fields. Migrations with large custom field schemas (100+ fields), activity histories exceeding 200,000 records, or multi-pipeline structures requiring extensive stage-mapping work extend to eight to fourteen weeks because of the manual export coordination, schema discovery complexity, and owner reconciliation steps. The lack of a documented ASPEC API does not extend the timeline significantly when the customer can provide direct database access, but it does when manual CSV exports are the only option.
