Overview
CompanyHub CRM stores contact records, company records, deals, tasks, notes, and custom tables in a schema that any admin can extend with freeform fields and table definitions. HubSpot receives these as Contacts, Companies, Deals, Tasks, Notes, and either native custom properties or custom objects (Enterprise tier). The migration reads CompanyHub's v1 REST API with start/limit pagination, extracting all standard objects and every custom table row with their field values and associations. The primary translation challenges are: CompanyHub's custom tables require a mapping decision per table (recreate as HubSpot custom objects, or collapse into custom properties on the standard object); CompanyHub hotness-scoring fields migrate as HubSpot custom number properties; UTrons automation workflows cannot migrate and are documented in full for rebuild inside HubSpot's workflow builder. HubSpot's lifecycle stage model has no direct CompanyHub equivalent, so contacts land with no lifecycle value and can be set post-migration using HubSpot lists or a bulk-update workflow. Owner resolution matches CompanyHub user emails to HubSpot user emails before assigning OwnerId. The delta-pickup window (24–48 hours) captures any new or modified records during the cutover window so HubSpot reflects the final CompanyHub state at go-live.

Object mapping
Each row shows how a CompanyHub 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.
CompanyHub CRM
Contact
HubSpot
Contact
1:1CompanyHub contact fields map directly to HubSpot contact properties. All standard fields (name, email, phone, job title, address) translate 1:1. The HubSpot contact record is created first, then associations to companies and deals are established after the related records exist in HubSpot.
CompanyHub CRM
Company
HubSpot
Company
1:1CompanyHub company records map to HubSpot company records. Company domain, industry, employee count, and annual revenue translate as HubSpot standard properties. CompanyHub parent-child hierarchies map using HubSpot's parent company association. Multi-company associations on a single contact collapse to one primary association in HubSpot with additional companies surfaced via company-to-contact associations.
CompanyHub CRM
Deal
HubSpot
Deal
1:1CompanyHub deals map to HubSpot deals (deals in HubSpot are also called opportunities internally). Deal name, amount, stage, close date, owner, and notes migrate directly. CompanyHub deal-stage names map value-by-value to HubSpot deal pipeline stages during import. Multiple CompanyHub deal pipelines map to multiple HubSpot deal pipelines.
CompanyHub CRM
Task
HubSpot
Task
1:1CompanyHub tasks migrate as HubSpot engagement tasks (internal tasks, not tickets). Task subject, body, due date, owner, and completion status are preserved. Tasks associated with a specific contact or deal carry the association forward in HubSpot so activity history remains linked to the correct record.
CompanyHub CRM
Note
HubSpot
Note
1:1CompanyHub notes migrate as HubSpot engagement notes attached to the relevant contact, company, or deal record. Note body text, create date, and owner are preserved. Notes associated with multiple records carry the primary association; secondary associations are documented in the migration plan for manual recreation if needed.
CompanyHub CRM
CompanyHub Owner
HubSpot
HubSpot Owner
1:1CompanyHub user records resolve to HubSpot owners by email address match. All records (contacts, companies, deals, tasks) carry their assigned owner in HubSpot. Unmatched owners (CompanyHub users without a HubSpot account) are flagged in the migration plan for team assignment before the full run. No record lands in HubSpot without an assigned owner.
CompanyHub CRM
Custom Table
HubSpot
Custom Object (Enterprise) or Custom Properties
1:1CompanyHub custom tables are mapped per-table based on complexity. Simple custom tables with primitive fields (text, number, date) are recreated as HubSpot custom properties on the related standard object. Complex custom tables with multiple columns and many-to-many associations are flagged for HubSpot custom object creation (requires Enterprise). A mapping plan is delivered before migration so custom object schemas are pre-created in HubSpot.
CompanyHub CRM
Custom Field (freeform on Contact, Company, Deal)
HubSpot
Custom Property on Contact, Company, or Deal
1:1CompanyHub freeform custom fields on any standard object migrate as HubSpot custom properties with the same label and field type. Text fields map to single-line or multi-line text properties. Number fields map to HubSpot number properties. Date fields map to HubSpot date properties. Pick-list fields in CompanyHub map to HubSpot dropdown or radio-button properties with the same options.
CompanyHub CRM
Hotness (scoring field)
HubSpot
Custom Number Property on Contact
1:1CompanyHub's one-click hotness meter (very hot / hot / warm / cold) does not translate to HubSpot's lifecycle stage model. The numeric or label-based hotness value migrates as a HubSpot custom property (e.g., Hotness_Score__c or Hotness_Label__c). Post-migration, teams can use HubSpot's property-based scoring actions to build automated scoring workflows aligned to their sales process.
CompanyHub CRM
Email / Bulk Mail Activity
HubSpot
Engagement Email (on Contact record)
1:1CompanyHub email tracking data (opens, clicks, sent timestamps) migrates as engagement records attached to the contact. Bulk mail campaign headers and send dates are preserved in a custom property or as engagement notes. The email body content is not included in the migration unless the email was stored as a note. Individual email send/receive logs migrate as engagement timeline entries.
CompanyHub CRM
Attachment
HubSpot
File (on associated record)
1:1CompanyHub file attachments associated with contacts, companies, or deals are downloaded and re-uploaded to HubSpot Files, then associated to the relevant record. File size limits apply (HubSpot default: 25MB per file). Inline images in notes are downloaded and rehosted in HubSpot's file storage.
CompanyHub CRM
UTrons (automation workflows)
HubSpot
HubSpot Workflows
1:1CompanyHub UTrons cannot be exported or migrated. Each Utron is documented in full with its trigger conditions, action steps, and branching logic so a HubSpot administrator can rebuild it in the workflow builder. The migration plan includes a Utron audit export that lists every active workflow, its trigger event, and the sequence of actions it performs. Workflow rebuild is outside the migration scope.

Pair-specific challenges
Migration approach
Connect to CompanyHub API and audit data structure
FlitStack authenticates to CompanyHub using your API keys (up to 5 keys managed from Settings > Integrations) and the v1 REST endpoint (https://api.companyhub.com/v1/). We pull all standard objects (contacts, companies, deals, tasks, notes) using start/limit pagination, then enumerate every custom table definition to understand column types and association schemas. The audit output includes record counts per object, a list of all custom tables with column definitions, active Utron workflow definitions, and a summary of owner and territory configurations. This phase produces the migration scope document before any data moves.
Map fields and custom tables; pre-create HubSpot properties
Every CompanyHub field (standard and custom) is mapped to a HubSpot property by name and type. Custom fields are pre-created in HubSpot before the migration run so property IDs exist at import time. Custom tables are classified per-table: simple tables become HubSpot custom properties; complex tables are flagged for custom object creation (or mapped to a custom property schema if the HubSpot plan is below Enterprise). Utron workflows are documented in full for rebuild. Owner resolution matches CompanyHub user emails to HubSpot user emails — any unmatched owners are reported for manual assignment before the full run.
Run a sample migration with field-level validation
A representative slice of records (typically 100–500 per object type spanning contacts, companies, deals, and activities) is migrated first. FlitStack generates a field-level comparison report showing source values against destination values for every mapped field. You can verify that deal stage names translated correctly, owner assignment resolved by email match, custom property values landed in HubSpot, and timestamp fields preserved their original dates. Any mapping errors are corrected before the full run commits. The sample run also validates that multi-object associations (contact-to-company, deal-to-contact) resolved in the correct order.
Execute full migration with delta-pickup window
The full migration runs in dependency order: companies first, then contacts, then deals, then tasks and notes. Foreign keys (contact-to-company, deal-to-contact associations) resolve using the previously migrated IDs. After the main migration window closes, a delta-pickup window (24–48 hours) captures any records created or modified in CompanyHub during the cutover. The audit log records every operation with timestamps, and one-click rollback is available if post-migration reconciliation finds unexpected discrepancies. No records are deleted from CompanyHub during this process — your CompanyHub instance remains read-accessible throughout.
Validate, deliver Utron rebuild specification, and close
Post-migration validation compares record counts, association counts, and a spot-check of field values between CompanyHub and HubSpot. The Utron rebuild specification (one document per Utron) is delivered as part of the handoff package. FlitStack reviews the specification with your HubSpot admin and confirms the rebuild plan for any workflows that are business-critical before go-live. Once validation sign-off is received, the migration project closes. A 30-day support window covers post-go-live questions and delta corrections if any records are found to be misaligned.
