Overview
Teams migrate from Star CRM to HubSpot when they want HubSpot's free starter tier, inbound marketing tools, and a CRM that grows with an inbound-first sales motion. The data model difference is structural: Star CRM likely uses a traditional relational schema with contacts, accounts, opportunities, and tasks stored as separate objects with explicit foreign-key relationships. HubSpot uses a property-based model where every record has a flat set of name-value properties, lifecycle stage governs contact routing, and deals reference contacts through an association graph rather than junction tables. FlitStack AI maps every Star CRM object to its HubSpot equivalent, preserves original timestamps as custom datetime properties, and resolves owner assignments by email-matching Star CRM users against HubSpot user accounts. Custom fields and pick-list values migrate as HubSpot custom properties. Association labels, activity history, and notes carry over as HubSpot engagements. The migration runs against HubSpot's CRM API with bulk endpoints where available, a delta-pickup window captures any records modified during cutover, and an audit log plus one-click rollback handles reconciliation failures.
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 Star 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.
Star CRM
Contact
HubSpot
Contact
1:1Star CRM contacts map 1:1 to HubSpot contacts. The primary company association is preserved as HubSpot's contact-to-company association using the association label feature. Additional company links from Star CRM become secondary associations in HubSpot, preserving multi-company contact relationships. Owner resolves by email match to HubSpot user accounts. The Star CRM contact ID is stored as source_system_id for traceability.
Star CRM
Account
HubSpot
Company
1:1Star CRM accounts map to HubSpot companies. Parent-child account hierarchies in Star CRM translate to HubSpot company associations using HubSpot's company hierarchy feature. Industry, employee count, and annual revenue map as direct properties where Star CRM stores them. Domain and website fields transfer directly to the HubSpot company record.
Star CRM
Opportunity
HubSpot
Deal
1:1Star CRM opportunities map to HubSpot deals. The deal name, amount, close date, and owner all transfer directly. Star CRM opportunity stage names map to HubSpot deal pipeline stages via value mapping. Probability values are preserved as custom properties on the deal since HubSpot manages probability at the pipeline stage level.
Star CRM
Pipeline
HubSpot
Deal Pipeline
1:1Star CRM pipelines map to HubSpot deal pipelines. Each Star CRM pipeline becomes one HubSpot pipeline with its own ordered stages, stage names, and probability settings. Stage probability and forecast category are preserved per stage in HubSpot's pipeline configuration. Pipeline-specific pick-list values require explicit value mapping rules.
Star CRM
Task
HubSpot
Engagement (Call)
1:1Star CRM tasks classified as call activities map to HubSpot engagements with type 'call'. Original call duration, outcome, and owner are preserved on the engagement record. HubSpot stores the call as an engagement record linked to the contact via the associations array. Task completion status maps to HubSpot engagement active/complete status.
Star CRM
Email / Email Log
HubSpot
Engagement (Email)
1:1Star CRM email logs migrate as HubSpot email engagements. Subject, body, timestamp, and associated contact link transfer directly. HubSpot's email tracking data (opens, clicks) is set to null since it originates post-migration. The engagement record preserves the original email timestamp from Star CRM.
Star CRM
Meeting / Calendar Event
HubSpot
Engagement (Meeting)
1:1Star CRM meeting records map to HubSpot meeting engagements. Start time, end time, title, body, and associated contacts all transfer as direct field mappings. HubSpot meeting engagements link to the contact record via the engagement associations array and preserve the original timestamp from Star CRM for accurate activity history continuity.
Star CRM
Note
HubSpot
Engagement (Note)
1:1Star CRM notes migrate as HubSpot note engagements. The note body, create timestamp, and owner transfer directly. HubSpot notes attach to the parent contact or company record via the associations array. Rich-text formatting in Star CRM notes is preserved where possible during the migration transfer.
Star CRM
Custom Field (Contact)
HubSpot
Custom Property (Contact)
1:1Star CRM custom fields on contacts create HubSpot custom properties. Text, number, date, and pick-list field types map to the corresponding HubSpot property type (text, number, date, enumeration). Pick-list values map value-by-value to HubSpot's option array for the custom property. Custom properties must be created via the CRM Properties API or portal before migration.
Star CRM
Custom Field (Opportunity)
HubSpot
Custom Property (Deal)
1:1Star CRM opportunity-level custom fields become HubSpot deal custom properties. Field-level validation rules from Star CRM do not transfer; HubSpot property validation is set to allow all values initially for data compatibility. Deal custom properties require pre-creation in HubSpot via the CRM Properties API before the migration writes data.
Star CRM
Custom Object
HubSpot
Custom Object
1:1Star CRM custom objects migrate 1:1 to HubSpot custom objects (available on HubSpot Professional and Enterprise tiers). Custom object associations require HubSpot junction objects when the source uses many-to-many relationships between custom objects and contacts or companies. The custom object schema must be configured in HubSpot before migration runs.
Star CRM
User / Owner
HubSpot
HubSpot User / Owner
1:1Star CRM user records are resolved by email match against HubSpot user accounts. Unmatched owners are flagged before migration; records for unmatched owners are assigned to a fallback HubSpot user specified by the customer. Star CRM user create dates are preserved as custom properties on the mapped owner record for audit continuity.

Migration approach
Stand up HubSpot schema before migration
Before any data moves, we deliver a HubSpot setup checklist based on the Star CRM field inventory. The checklist specifies every custom property to create (name, type, pick-list options), every deal pipeline and stage to configure, and the lifecycle stage values to add as HubSpot lifecyclestage options. We recommend creating HubSpot user accounts for every Star CRM owner at this stage so owner resolution runs cleanly. The schema must be live in HubSpot before the test migration validates field mapping. If HubSpot Professional or Enterprise is the destination and custom objects are in use, we also specify the custom object schema at this step.
Audit and clean Star CRM data
We pull a full export of Star CRM objects via the platform's API (contacts, accounts, opportunities, tasks, notes, meetings, and custom objects). The export is profiled for duplicates, missing required fields, and inconsistent pick-list values. Duplicate contacts are identified by email address and flagged for customer decision: merge before migration or import all and deduplicate in HubSpot post-migration. Records with missing required HubSpot fields (e.g., contact with no email) are flagged with the corrective action needed. This audit report is the basis for the migration field-mapping spreadsheet.
Run a sample migration with field-level diff
A representative slice of 100–500 records across contacts, companies, deals, and activities migrates first. We generate a field-level diff comparing each Star CRM field value against the corresponding HubSpot field after migration. The diff covers direct field mappings, transformed owner assignments, pick-list value mappings, and custom property transfers. The customer reviews the diff and approves field mapping logic before the full migration runs. Any mapping corrections are made to the migration script and a second sample run validates the fix.
Execute full migration with delta-pickup window
The full dataset migrates in dependency order: companies first (HubSpot requires a company to exist before a contact can associate to it), then contacts, then deals (deals reference contacts via association), then activities (engagements link to their parent records). A delta-pickup window of 24–48 hours after the full migration captures any records created or modified in Star CRM during the cutover period. All migration operations are written to an audit log with source record ID, destination record ID, operation type, and timestamp. If reconciliation detects missing records or mismatched counts, one-click rollback reverts the destination to its pre-migration state.
Validate and hand off rebuild reference for automations
After migration, we run a validation report comparing Star CRM record counts against HubSpot record counts per object and per custom property. Association integrity (contacts linked to companies, deals linked to contacts) is verified. The validation report is shared with the customer for sign-off. We also deliver a Star CRM workflow export — a structured document listing every Star CRM workflow, sequence, and automation with its trigger conditions and actions — as a reference for rebuilding in HubSpot's workflow engine. Integration reconnection steps are documented separately for the customer's IT team.
