Overview
Teams migrate to HubSpot from a disconnected CRM setup when they need a unified platform that combines sales, marketing, service, and content management without paying for separate integrations. The migration carries everything the source system stores natively — contacts with their properties, companies with association labels, deals with pipeline stages, engagement history, and custom objects — into HubSpot's object model using HubSpot's Contacts, Companies, Deals, and custom objects. HubSpot represents contacts as property-bags: every attribute is a labeled property with a type and an optional history-timestamp. Lifecycle stage is a native contact property; deal pipelines are separate objects with pick-list stages. Activities (calls, emails, meetings, notes) are engagement records linked to contact and company IDs with original timestamps and owners preserved. The FlitStack migration sequence loads companies first (no dependencies), then contacts with lifecycle and company associations, then deals with pipeline and stage mapping, then engagement records. Workflows, sequences, email templates, reports, and dashboards do not migrate — they are source-platform configuration that must be rebuilt in HubSpot's workflow engine and report builder. After data lands, FlitStack runs a delta-pickup window to capture in-flight changes during cutover, delivers a full audit log, and offers one-click rollback if reconciliation fails.

Object mapping
Each row shows how a Populate 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.
Populate
Contact
HubSpot
Contact
1:1Direct map. HubSpot contacts are property-bags: every attribute from the source contact maps as a named HubSpot property on the contact record. The source contact's primary company association maps to a HubSpot company association using HubSpot's association API. Contacts without a primary company in the source land in HubSpot without a company association and can be linked later.
Populate
Company
HubSpot
Company
1:1Direct map. HubSpot companies store name, domain, industry, employee count, annual revenue, and address as native properties. Source parent-child company hierarchies map to HubSpot's parent company association. Multi-company contacts collapse to a single primary company association in HubSpot, with additional associations surfaced as secondary links.
Populate
Deal
HubSpot
Deal
1:1Direct map. HubSpot deals carry deal name, amount, close date, pipeline, stage, and owner as native properties. Source deal custom properties map as HubSpot deal properties. Each deal links to a HubSpot pipeline object whose stage pick-list values are scoped to that pipeline only, matching the source pipeline's stage set.
Populate
Pipeline
HubSpot
Pipeline
1:1Direct map. HubSpot pipelines are native objects separate from deals. Each source deal pipeline becomes one HubSpot pipeline. The source pipeline's stage names and order map to HubSpot pipeline stage names in the same sequence. Stage probability values from the source are preserved as metadata for reporting continuity.
Populate
Engagement (Call)
HubSpot
Engagement (Call)
1:1Direct map. Source call records migrate as HubSpot engagement records with type 'Call.' The call subject, duration, direction (inbound/outbound), outcome, and original timestamp migrate to HubSpot engagement properties. The call is linked to the associated contact ID so it appears in the contact's timeline.
Populate
Engagement (Email)
HubSpot
Engagement (Email)
1:1Direct map. Source email engagement records migrate as HubSpot engagement records with type 'Email.' The email subject, body text, and original timestamp migrate to HubSpot engagement properties. Attachments referenced in the source email are re-uploaded as HubSpot Files and linked to the engagement record.
Populate
Engagement (Meeting)
HubSpot
Engagement (Meeting)
1:1Direct map. Source meeting records migrate as HubSpot engagement records with type 'Meeting.' The meeting title, start time, end time, location, and associated contacts map to HubSpot engagement properties. The original timestamp and owner are preserved so the meeting appears in the contact and company timeline at the correct date.
Populate
Engagement (Note)
HubSpot
Note
1:1Direct map. Source note records migrate as HubSpot notes on the associated contact or company. The note body text, creation timestamp, and owner are preserved. If the source note is associated with multiple records, FlitStack creates a primary note on the contact and attaches it to additional records via HubSpot's association API.
Populate
Owner
HubSpot
Owner
1:1Direct map. Source owner records resolve to HubSpot owners by email address match. Owner name, email, and HubSpot owner ID are mapped so all records in HubSpot carry the correct owner. Source owners without a matching HubSpot user email are flagged before migration so the team can either invite them to HubSpot or reassign their records.
Populate
Custom Object
HubSpot
Custom Object
1:1Direct map on HubSpot Enterprise. Source custom objects migrate to HubSpot custom objects 1:1. Custom object associations that use a many-to-many relationship in the source require HubSpot junction objects — FlitStack surfaces this in the migration plan so the HubSpot admin can pre-create the junction object schema before data lands.
Populate
Attachment / File
HubSpot
HubSpot File
1:1Direct map. Source file attachments on contacts, companies, and deals are downloaded and re-uploaded as HubSpot Files, then linked to the associated CRM record. Files larger than HubSpot's 25 MB per-file limit are flagged for manual handling. Inline images embedded in notes are extracted, rehosted as HubSpot Files, and the image URLs are updated in the note body.
Populate
Workflow / Sequence
HubSpot
HubSpot Workflow
1:1No direct migration. Workflows and sequences are automation logic stored in the source system, not data attached to records. HubSpot has no native equivalent for sequences. FlitStack exports the source workflow definitions as a structured reference document and shares it with the team so the HubSpot admin can rebuild the logic in HubSpot's Workflows tool.
Populate
Role / Permission Set
HubSpot
HubSpot Team / User Permission
1:1Roles, permissions, and sharing rules are destination‑side access‑control configuration that has no direct migration path. HubSpot models access using Teams, Roles, and individual user permissions, which must be configured separately after data lands. FlitStack exports a permission inventory from the source — listing each role, its associated users, and any sharing rules — so the HubSpot admin can recreate the same access hierarchy in HubSpot's access‑control settings.
Populate
Integration / Connected App
HubSpot
HubSpot Integration
1:1Third-party integrations and connected apps are connection credentials scoped to the source platform, not transferable data. Each integration must be rebuilt in HubSpot using HubSpot's app marketplace connectors, private apps, or custom API integrations. The source integration list serves as an inventory for the rebuild plan, and FlitStack can provide a checklist of required scopes and callback URLs for each integration.
Populate
Report / Dashboard
HubSpot
HubSpot Report / Dashboard
1:1Reports and dashboards are source-platform configuration, not data. HubSpot's report builder uses HubSpot-native objects and properties, so source reports cannot be imported directly. The underlying data migrates; the report and dashboard definitions must be rebuilt in HubSpot's analytics tools.
Populate
Custom Object Association
HubSpot
HubSpot Custom Object Association
1:1Custom object associations that use a many-to-many relationship in the source require HubSpot junction objects. FlitStack surfaces this in the migration plan so the HubSpot admin can pre-create the junction object schema before data lands.
Populate
Custom Field (Unmapped)
HubSpot
HubSpot Custom Property
1:1Source custom fields that have no direct HubSpot equivalent are preserved as custom properties in HubSpot. The team decides on naming, type, and pick-list options before migration so FlitStack can create the properties and map values correctly.

Migration approach
Audit source data and build HubSpot schema plan
FlitStack inventories all source objects, standard properties, custom fields, custom objects, deal pipelines with their stages, engagement types, owner records, and workflow definitions. We then deliver a HubSpot setup plan: a list of HubSpot properties to create (including custom properties for unmapped source fields), the HubSpot tier required for custom-object support, a pipeline-creation checklist with stage names in the correct order, and a value-mapping table for pick-list fields that differ between platforms. This plan is the shared contract between FlitStack and the team before any data moves.
Resolve owners and validate HubSpot user access
Source owner records are matched to HubSpot user accounts by email address. FlitStack generates a pre-migration owner match report showing which source owners have a corresponding HubSpot user, which do not, and which have duplicate email candidates. The team resolves unmatched owners by inviting them to HubSpot or designating a fallback owner before the migration run. No record migrates without a valid HubSpot owner — unowned records are flagged for manual assignment rather than left orphaned.
Migrate in dependency order: companies, then contacts, then deals, then engagements
HubSpot requires companies before contacts (via the associatedcompanyid lookup) and contacts before deals (via deal-contact associations). FlitStack sequences the migration so foreign keys resolve correctly. Companies load first. Contacts load second with lifecycle stage, lead status, and company association mapping applied. Deals load third with pipeline and stage value mapping per deal. Engagement records (calls, emails, meetings, notes) load last, linked to the contact and company IDs created in the previous steps. Each phase includes a record-count validation against the source before the next phase begins.
Run a sample migration and generate a field-level diff
A representative slice of data — typically 100–500 records spanning contacts, companies, deals, and engagement records — migrates first. FlitStack generates a field-level diff report that compares source field values to the HubSpot field values for every mapped property. The team reviews the diff to verify that lifecycle stage mapping, pipeline-stage mapping, owner resolution, and company association are working as expected before the full migration commits. Any mapping corrections are made before the production run.
Full migration with delta-pickup and rollback readiness
The full migration runs against HubSpot. After the initial load completes, a delta-pickup window (typically 24–48 hours) captures any records created or modified in the source CRM during the cutover period. FlitStack generates a full audit log of every record created, updated, or skipped. If reconciliation reveals a mapping error or data quality issue, one-click rollback reverts all migration operations so the team can correct the plan and re-run without leaving HubSpot in an inconsistent state.
