Overview
CRM Service and HubSpot model customer data differently: CRM Service typically uses a flat record structure with standalone objects for contacts and companies, while HubSpot employs a unified object graph where contacts and companies are distinct but associated through a many-to-many relationship model. HubSpot also introduces lifecycle_stage as a native property on contacts, deal pipelines with stage-specific probability weighting, and a tickets object for service management. FlitStack AI sequences the migration so parent objects (companies, contacts) land first, followed by deals and tickets with their foreign-key relationships intact. Custom fields from CRM Service migrate as HubSpot custom properties — your admin reviews the property list before the migration runs. Workflows, automation sequences, and email templates do not transfer and must be rebuilt in HubSpot's workflow builder. The migration uses CRM Service's API export and HubSpot's native import API, with a delta-pickup window capturing any records modified during the cutover period.
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 CRM Service 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.
CRM Service
Contact
HubSpot
Contact
1:1CRM Service contacts map directly to HubSpot contacts. HubSpot's contact model supports email, phone, job title, address, and lifecycle_stage as native properties. Contacts without a primary company in CRM Service land in HubSpot as standalone contacts and can be associated to companies via the Companies object post-migration.
CRM Service
Company
HubSpot
Company
1:1CRM Service company records map to HubSpot companies. HubSpot's Company object includes name, domain, industry, employee count, annual revenue, phone, and address properties. Parent-child company hierarchies in CRM Service map to HubSpot's parent company association on the Company record, preserving corporate structure relationships across the migration.
CRM Service
Deal
HubSpot
Deal
1:1CRM Service deals map to HubSpot deals. Each deal in CRM Service is associated with a primary company and optionally a contact. HubSpot deals carry amount, close date, pipeline, deal stage, and owner. Stage names are mapped value-by-value from CRM Service to the corresponding HubSpot pipeline stage.
CRM Service
Deal Stage
HubSpot
Deal Stage
1:1CRM Service deal stages map to HubSpot pipeline stages using value mapping. Each CRM Service stage is matched to a HubSpot stage by name or semantic equivalent. If CRM Service has stages that have no HubSpot equivalent, your admin chooses a fallback stage and the original stage label is preserved in a custom property.
CRM Service
Ticket / Case
HubSpot
Ticket
1:1CRM Service tickets or cases map to HubSpot tickets. HubSpot's Ticket object has status, priority, pipeline, resolution SLA, and source channel properties. If CRM Service ticket data includes fields not present in HubSpot's standard ticket schema, those migrate as custom properties on the ticket record.
CRM Service
Task / Activity
HubSpot
Engagement (Task)
1:1CRM Service tasks and activities (calls logged, emails sent, notes) map to HubSpot engagements. HubSpot engagements preserve the original timestamp, owner, and association to the contact or company record. The engagement type (call, email, meeting, note) is stored in the engagement type property.
CRM Service
Owner / User
HubSpot
User
1:1CRM Service owner records are resolved to HubSpot users by email match. If a CRM Service owner email matches a HubSpot user email, the ownerId maps directly. Unmatched owners are flagged as a pre-migration step — your team either creates HubSpot users or assigns records to a fallback owner before the migration runs.
CRM Service
Custom Fields
HubSpot
Custom Properties
1:1CRM Service custom fields that do not have a HubSpot native equivalent are created as HubSpot custom properties. Your admin reviews the property list before migration to rename, merge, or discard source custom fields. Custom properties are created in HubSpot's property settings and then populated during the migration run.
CRM Service
Attachment / File
HubSpot
File
1:1CRM Service file attachments associated with contacts, companies, or deals are downloaded and re-uploaded to HubSpot Files. HubSpot Files are associated to records via the file upload API. File size limits from the source platform are respected; files exceeding HubSpot's limit are flagged for manual handling.
CRM Service
Lead / Prospect
HubSpot
Contact (lifecycle_stage)
1:1CRM Service leads or prospects without a closed-won deal are migrated as HubSpot contacts. HubSpot's lifecycle_stage property reflects the lead status: 'Lead' for unqualified prospects and 'Customer' for those with associated closed-won deals. The original source system status is preserved in a custom property for reporting continuity.
CRM Service
Association Label
HubSpot
Contact-to-Company Association
1:1CRM Service contact-to-company association labels (if present) map to HubSpot's association labels. HubSpot supports association labels on the Contact-to-Company relationship such as 'Business', 'Partner', or 'Press'. Labels that cannot be mapped are preserved as a custom contact property for reference.
CRM Service
Campaign / List
HubSpot
HubSpot List (static)
1:1CRM Service campaign membership or static lists have no direct HubSpot equivalent at the CRM level. CRM Service list membership is preserved as a custom contact property (e.g., List_Name__c) so lists can be rebuilt as HubSpot static lists post-migration. Dynamic lists require rebuild using HubSpot's list filters.

Migration approach
Run discovery scan on CRM Service and HubSpot target environment
FlitStack AI connects to CRM Service via API and exports a full inventory of objects, fields, custom fields, and record counts. Simultaneously, we connect to your HubSpot account to inventory existing properties, pipelines, and ticket pipelines. The discovery report lists every field that needs mapping, flags CRM Service custom fields without HubSpot equivalents, and estimates the total migration record count for pricing confirmation.
Build field mapping spreadsheet and submit for admin review
Our mapping engine generates a field-level mapping spreadsheet covering all standard objects (Contact, Company, Deal, Ticket) and every CRM Service custom field. Your HubSpot admin reviews the mapping, renames or discards source fields, and approves the final property list. We create the custom properties in HubSpot via API before the migration run. This step typically takes 1–3 business days depending on the number of custom fields.
Resolve owner and user records by email match
CRM Service owner IDs are matched against HubSpot user emails. For each unmatched owner, FlitStack surfaces a pre-migration action item: either create a HubSpot user with that email or assign their records to a fallback owner. This owner resolution step is completed before the migration run to ensure no records land without a valid HubSpot owner, preventing orphaned records in the target system.
Run sample migration with field-level diff
A representative slice of records (typically 100–500 per object) migrates first. FlitStack generates a field-level diff showing the source value, mapped value, and destination value for every field. You verify lifecycle_stage mapping, deal stage mapping, owner resolution, and association integrity before the full run commits. This catches mapping errors while the blast radius is small and reduces risk before committing to the full dataset.
Execute full migration with delta-pickup window
The full migration runs against CRM Service and HubSpot. After the initial run completes, a delta-pickup window (typically 24–48 hours) polls CRM Service for records created or modified since the migration started. All in-flight records are captured and synced to HubSpot before the delta window closes. An audit log records every operation, and one-click rollback reverts the HubSpot target if reconciliation fails.
