CRM migration
Field-level mapping, validation, and rollback between Omni.us and HubSpot. We move data and schema; workflows are rebuilt natively in HubSpot.

Overview
Omni.us stores CRM data in a flat object model with custom fields, association labels, and owner-based record assignment. HubSpot uses a relational object graph with Contacts, Companies, Deals, and a lifecycle stage property that drives marketing and sales segmentation. The migration carries every standard object (contacts, companies, deals, activities) into HubSpot's corresponding objects, maps Omni.us owner IDs to HubSpot user emails by matching, and preserves original create/update timestamps as custom datetime fields. Omni.us custom fields translate to HubSpot custom properties — some directly, others requiring HubSpot Operations Hub for type-aware mapping. Workflows, sequences, and automation logic in Omni.us do not migrate; FlitStack exports those definitions as a rebuild reference for HubSpot workflows. The cutover uses a delta-pickup window so records modified during the switch land in HubSpot with their final state. All data moves through HubSpot's native import API and bulk import tools, with field-level validation before final commit. This includes preserving Omni.us association labels as HubSpot association labels, mapping pick-list values manually in HubSpot before migration, and handling owner resolution by email match with fallback assignment for unmatched owners.
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 Omni.us 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.
Omni.us
Contact
HubSpot
Contact
1:1Omni.us contacts map 1:1 to HubSpot contacts. Email, name, phone, job title, and address fields translate directly. Omni.us owner ID resolves to HubSpot user by email match; unassigned contacts land under a default owner flagged for review. Original create and update timestamps are preserved as custom datetime fields in HubSpot.
Omni.us
Company
HubSpot
Company
1:1Omni.us companies map to HubSpot companies. Company name, domain, industry, employee count, and annual revenue map directly. Parent-company hierarchies in Omni.us translate to HubSpot's parent company field using ID-based linking. Industry pick-list values require value mapping to HubSpot's standard industry list.
Omni.us
Deal
HubSpot
Deal
1:1Omni.us deals map to HubSpot deals with amount, close date, and stage preserved as direct field mappings. Deal name becomes dealname in HubSpot. Owner resolution happens by email match to HubSpot users before deal creation. The Omni.us deal ID is stored in a custom property for traceability and de-duplication.
Omni.us
Deal Pipeline
HubSpot
Pipeline
1:1Omni.us deal stages map to HubSpot pipeline stages. Each Omni.us deal type or category creates a corresponding HubSpot pipeline with its own stage set. Stage order and names are preserved during migration; probability values are configurable post-migration in HubSpot's pipeline settings. Multiple deal types from Omni.us result in multiple HubSpot pipelines.
Omni.us
Activity (Call/Email/Meeting)
HubSpot
Engagement
1:1Omni.us call, email, and meeting activities become HubSpot engagements with original timestamps, owner attribution, and parent-record association preserved. Activity type (call, email, meeting) maps to HubSpot engagement type (CALL, EMAIL, MEETING). FlitStack normalizes timestamps to UTC during the transform step before importing to HubSpot.
Omni.us
Note
HubSpot
Note
1:1Omni.us notes migrate to HubSpot notes with body content and original create timestamps preserved. Notes associate to the parent record (contact, company, or deal) by Omni.us record linkage using HubSpot's association API. Rich-text formatting is preserved where Omni.us supports it; inline images are extracted and rehosted as HubSpot-hosted files.
Omni.us
Custom Field (text/number/date)
HubSpot
Custom Property
1:1Omni.us custom fields on contacts, companies, and deals create HubSpot custom properties via the HubSpot Properties API. Field type parity determines mapping: text maps to string, number maps to number, date maps to datetime. Custom properties require HubSpot Operations Hub on Starter and Professional tiers to create beyond the default limit.
Omni.us
Custom Field (pick-list)
HubSpot
Custom Property (picklist)
1:1Omni.us pick-list fields map to HubSpot drop-down custom properties with value-by-value translation. Pick-list option labels are preserved verbatim during migration. Option values must be pre-created in HubSpot's property settings before the migration run; order may be reconfigured post-migration in HubSpot's UI.
Omni.us
Association Label
HubSpot
Association Label
1:1Omni.us contact-to-company and contact-to-deal association labels migrate as HubSpot association labels using the Associations API. Decision-maker, influencer, and other role labels transfer directly. HubSpot supports labeled associations on the Contact, Company, and Deal records with multiple label types per association.
Omni.us
Attachment/File
HubSpot
File
1:1Omni.us file attachments download and re-upload to HubSpot Files using the Files API, attached to the corresponding record (contact, company, or deal) via the associations API. File size limits apply per HubSpot tier (100MB Starter, 10GB Professional, 25GB Enterprise). Inline images in notes are extracted and rehosted as HubSpot-hosted files.
Omni.us
Owner/User
HubSpot
User
1:1Omni.us owner records resolve to HubSpot users by email address match using the HubSpot Users API. If a HubSpot user account does not exist for an Omni.us owner, the owner is flagged in the migration audit and records are assigned to a fallback owner designated before migration runs.
Omni.us
System ID / Audit Trail
HubSpot
Custom Field (Source_System_ID__c, Original_Create_Date__c)
1:1Omni.us internal record IDs are stored in HubSpot custom properties (Source_System_ID__c) for traceability and delta-run de-duplication. Original create and update timestamps from Omni.us are preserved as custom datetime fields (Original_Create_Date__c, Original_Update_Date__c) since HubSpot's native timestamps reflect migration time.

Migration approach
Audit Omni.us data model and HubSpot destination setup
FlitStack extracts Omni.us object definitions, custom field configurations, pick-list values, and owner list via the Omni.us API. Simultaneously, we assess the destination HubSpot portal's tier, existing pipelines, custom property definitions, and user list. This audit produces a data mapping schema that identifies direct field mappings, pick-list value mappings, and custom property creation requirements. The audit also surfaces any HubSpot tier limitations on custom property counts so you can add Operations Hub if needed before migration planning finalizes.
Resolve owners and create HubSpot custom properties
FlitStack matches Omni.us owner email addresses against HubSpot user accounts. Owners without HubSpot counterparts are flagged and assigned to a fallback owner designated by your team. Meanwhile, FlitStack delivers a property creation checklist for all Omni.us custom fields and pick-list values that need HubSpot custom properties — your HubSpot admin creates these properties in HubSpot before the migration run so the schema is ready for incoming data.
Run a sample migration with field-level validation
A representative slice of records (typically 100–500 spanning contacts, companies, deals, and activities) migrates first. FlitStack generates a field-level diff between the Omni.us source values and the HubSpot destination values so you can verify that pick-list mappings are correct, custom property values landed as expected, owner resolution worked, and timestamps are accurate. You approve the sample before the full migration run commits.
Execute full migration with delta-pickup cutover
The full dataset migrates to HubSpot using HubSpot's native import API. After the initial load, a delta-pickup window (typically 24–48 hours) captures any Omni.us records created or modified during the cutover period. FlitStack generates an audit log of every record migrated, its source Omni.us ID, destination HubSpot ID, and timestamp. One-click rollback reverts the HubSpot portal to pre-migration state if reconciliation reveals issues. After rollback window closes, the HubSpot portal is your system of record.
