Overview
Crust CRM organizes data around customizable modules with relationships defined through its internal association model, while HubSpot uses Contacts, Companies, Deals, and custom Properties tied to a lifecycle-stage framework. The migration challenge is threefold: translating Crust's flexible module architecture into HubSpot's object graph, mapping Crust's deal stages to HubSpot's pipeline stages with probability weighting, and preserving any custom fields as HubSpot custom properties (HubSpot Enterprise only for custom objects). FlitStack AI extracts Crust data via its API using the account's configured object types and field labels, transforms field values to HubSpot conventions (lowercase property names, pick-list standardization), and loads through HubSpot's CRM API or bulk import depending on record volume. We surface Crust workflows, automation rules, and any custom module associations that have no HubSpot equivalent — those require manual rebuild in HubSpot's workflow editor or Salesforce Connector-style integration tools. The migration runs with scoped read access on Crust, leaving your team operational throughout, with a 24–48 hour delta-pickup window capturing in-flight changes before final go-live.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Crust CRM object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Crust CRM
Contact
HubSpot
Contact
1:1Crust contacts map directly to HubSpot contacts. Email address serves as the unique identifier for matching records between systems. Owner resolution matches Crust owner email to HubSpot user email for proper assignment. Contacts without a primary company link land as standalone HubSpot contacts, and we preserve the original Crust create date as a custom property for historical reference.
Crust CRM
Company / Account
HubSpot
Company
1:1Crust company records map 1:1 to HubSpot companies without transformation. The company domain field maps to HubSpot's domain property for automatic contact-company association upon import. Parent-company hierarchies in Crust map via HubSpot's parent company association, preserving organizational structure through the migration.
Crust CRM
Deal / Opportunity
HubSpot
Deal
1:1Crust deals map to HubSpot deals as the core revenue object. Each Crust deal stage maps to a HubSpot pipeline stage with probability values transferred as custom numeric fields if HubSpot's probability per stage doesn't match Crust's custom probability model. Deal owner assignments resolve via email matching similar to contact ownership.
Crust CRM
Custom Module (Enterprise)
HubSpot
Custom Object (HubSpot Enterprise)
1:1Crust custom modules require HubSpot Enterprise custom objects at the destination. Each module maps as a named custom object with its Crust fields represented as custom properties. N:N module associations between modules need HubSpot junction-object equivalents, which FlitStack AI structures using association properties during migration.
Crust CRM
Activity Log / Note
HubSpot
Engagement / Note
1:1Crust activity logs including notes, call logs, and meeting records map to HubSpot engagements with original timestamps preserved for audit continuity. Call activities map to HubSpot logged calls; meeting records map to HubSpot meetings with duration and attendees captured in the engagement properties.
Crust CRM
Task
HubSpot
Task
1:1Crust tasks map to HubSpot tasks with subject, due date, priority, and owner preserved. Completed status transfers directly to HubSpot's task completion field. Overdue logic and reminder settings are destination-side configuration that your team sets post-migration based on HubSpot's task notification settings.
Crust CRM
Attachment / File
HubSpot
Files (HubSpot File Manager)
1:1Crust file attachments re-upload to HubSpot Files using the bulk file import mechanism. Files are linked to the parent record (contact, company, or deal) via HubSpot's file association model using association type IDs. File size limits per HubSpot's storage tier apply and are validated during the import pass.
Crust CRM
Owner / User
HubSpot
User
1:1Crust owner records resolve by email match against HubSpot users in the destination account. Unmatched owners are flagged and reported before migration begins. Your team either creates HubSpot user accounts for unmatched owners first or assigns those records to a designated fallback owner during the migration pass.
Crust CRM
Tag / Label
HubSpot
HubSpot property or list
1:1Crust tags applied to contacts or companies map to HubSpot properties if the tag set is finite and manageable within HubSpot's property constraints. High-cardinality tags with many unique values may need to remain as custom properties rather than HubSpot lists to avoid property enumeration limits.
Crust CRM
Workflow / Automation
HubSpot
HubSpot Workflow (manual rebuild required)
1:1Crust workflows, triggers, and automation rules do not migrate to HubSpot due to incompatible schema formats. We export the workflow definitions as a structured JSON reference document including trigger conditions, action steps, and filter logic so your HubSpot admin can rebuild them in HubSpot's workflow editor.
Crust CRM
Custom field on Contact (non-standard)
HubSpot
Custom property on Contact
1:1Any Crust contact property that doesn't match HubSpot's standard contact property schema migrates as a HubSpot custom property. Property type matching includes text, number, date, and picklist formats aligned to HubSpot's supported custom property types during migration.
Crust CRM
Pipeline Stage (Crust)
HubSpot
Pipeline Stage (HubSpot)
1:1Crust deal stages map value-by-value to HubSpot pipeline stages using a configured mapping table. Each Crust stage name becomes a HubSpot stage name within your target pipeline. Stage order and probability percentages are preserved as configured in Crust, transferred to HubSpot's pipeline stage settings.

Pair-specific challenges
Migration approach
Discover Crust schema and HubSpot destination configuration
FlitStack AI reads your Crust CRM object schema via its API — identifying all standard objects, custom modules, field labels, and pick-list values. We simultaneously review your target HubSpot account (or set one up) to confirm which HubSpot tier you're on, which pipelines exist, and whether custom object creation is available. The output is a field-mapping spreadsheet showing every Crust field, its HubSpot destination, and the mapping type (direct, value-map, custom field required).
Resolve owner and user records before data migration
Crust owner records are matched to HubSpot users by email address as the join key. We generate an owner-resolution report listing matched users, unmatched Crust owners, and a fallback-owner assignment plan. Your team creates HubSpot user accounts for any unmatched owners before the migration runs — no record lands in HubSpot without a valid owner assignment to maintain accountability and follow-up responsibility in the destination system.
Migrate companies and contacts first, then deals and custom objects
HubSpot's object model requires companies to exist before contacts can associate to them, and contacts to exist before deals can use contact roles. We sequence the migration: companies → contacts → deals → custom objects. Each batch is validated (record counts, field coverage, association integrity) before the next batch starts. Any Crust custom modules that depend on contacts or companies are migrated last.
Run a sample migration with field-level diff before full commit
A representative slice of 200–500 records (spanning contacts, companies, deals, and any custom modules) migrates first. We generate a field-level diff between the Crust source values and the HubSpot destination values so you can verify that lifecycle stage mapping, pipeline stage mapping, owner resolution, and custom property transfer match your expectations. You approve the diff before the full migration runs.
Execute full migration with delta-pickup and rollback readiness
The full migration runs against your HubSpot account using the validated mapping. A delta-pickup window (24–48 hours) captures any records created or modified in Crust during the migration window. FlitStack AI logs every operation to an audit trail. If reconciliation reveals data quality issues, one-click rollback reverts the HubSpot state to the pre-migration snapshot so you can correct the mapping and re-run.
