Overview
RetainUser CRM stores contacts and companies with flat property lists and basic deal stages — no native lifecycle-stage tracking, no scoped pipeline stages, and a simple owner assignment model. HubSpot uses a dedicated lifecycle_stage property on contacts, pipeline-scoped deal stages, and an engagement timeline that tracks calls, emails, meetings, and notes as first-class objects. The migration carries everything RetainUser stores natively — contacts, companies, deals, custom properties, activities, and owner data — into HubSpot's object model. The harder translation work is mapping RetainUser's flat contact properties to HubSpot's structured lifecycle_stage field, handling the absence of contact-role assignments in RetainUser when HubSpot requires a primary contact role on every deal, and scoping deal stage values correctly when multiple HubSpot pipelines are in use. We run a test migration against a representative slice of your data first, generate a field-level diff, and execute the full migration with a 24–48-hour delta pickup window to capture in-flight changes during cutover. Workflows, email templates, SMS sequences, and automation logic from RetainUser do not migrate — those require rebuild in HubSpot's workflow builder, and we export your RetainUser workflow definitions as a reference document for that rebuild.

Object mapping
Each row shows how a RETAINUSER 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.
RETAINUSER CRM
Contact
HubSpot
Contact
1:1Direct map. RetainUser contact properties migrate as HubSpot contact properties. HubSpot's dedicated lifecycle_stage field does not exist in RetainUser — we populate it from a source property or set a default value based on your configuration. Original create timestamps are preserved as a custom datetime property.
RETAINUSER CRM
Company
HubSpot
Company
1:1Direct map. RetainUser company records map to HubSpot company records. HubSpot supports company hierarchies via the parent company ID field. Multi-contact companies in RetainUser associate cleanly to the same HubSpot company record — no duplication risk if name/domain matching is applied.
RETAINUSER CRM
Deal
HubSpot
Deal
1:1Direct map. RetainUser deal records map to HubSpot deal records. Deal stages from RetainUser are mapped to HubSpot pipeline stages — we apply a default stage mapping and surface the mapping plan for your review before the migration runs so you can adjust stage values per HubSpot pipeline.
RETAINUSER CRM
Contact role on deal
HubSpot
Deal contact role
1:1RetainUser does not enforce contact roles on deal associations — contacts can be attached to a deal without a role label. HubSpot requires a role (scheduler, contract-sender, other, etc.) on every contact linked to a deal. We assign a default role (configurable — typically 'Other') to all RetainUser contacts on deals that have no explicit role in the source. Role assignment can be reviewed and updated post-migration in HubSpot's deal contact association UI.
RETAINUSER CRM
Owner
HubSpot
Owner
1:1RetainUser owner IDs are resolved to HubSpot owners by email address match. Unmatched owners are flagged before the migration commits — your team either creates HubSpot user records for those owners or assigns their records to a fallback owner. No record lands in HubSpot without a resolved owner.
RETAINUSER CRM
Call activity
HubSpot
Call
1:1Direct map. RetainUser call logs become HubSpot call engagement records. The migration copies call direction (inbound/outbound), duration, start timestamp, owner email, and the associated contact and deal into the HubSpot Call object. Disposition notes from RetainUser populate the HubSpot call body field; outcome codes are translated to free-text notes if no direct mapping exists. Attachments linked to the call are uploaded to HubSpot Files and reattached.
RETAINUSER CRM
Email activity
HubSpot
Direct map. RetainUser email records become HubSpot email engagement records. The migration copies the subject line, body, sent timestamp, owner email, and the associated contact and deal into the HubSpot Email object. If RetainUser stores threaded conversations, each message appears as a separate email engagement linked to the same contact/deal. Inline images are extracted, rehosted in HubSpot Files, and the body is updated with the new URLs.
RETAINUSER CRM
Meeting / appointment
HubSpot
Meeting
1:1Direct map. RetainUser meeting records become HubSpot meeting engagement records. The migration copies the meeting title, start and end timestamps, owner email, and the associated contact and deal into the HubSpot Meeting object. Location, description, and any attachments are transferred as HubSpot Files and linked. Recurring meetings are broken into individual meeting records. HubSpot displays each meeting on the contact and deal engagement timeline for full visibility.
RETAINUSER CRM
Note
HubSpot
Note
1:1Direct map. RetainUser notes become HubSpot notes. The migration copies the note body, associated contact and company IDs, and the original creation timestamp into the HubSpot note record. Rich-text is converted to plain text; embedded images are rehosted as HubSpot Files and linked in the note body. Large notes are transferred in full without truncation, and the original RetainUser note ID is stored as a custom property.
RETAINUSER CRM
Custom fields (property_type, agent_name, listing_date, etc.)
HubSpot
Custom properties on Contact / Deal
1:1RetainUser custom fields without a direct HubSpot equivalent (property-specific fields like property_type, square_footage, agent_name, listing_date, bedrooms, bathrooms, status) are created as HubSpot custom properties during the migration setup phase. We create them in HubSpot before data lands so field-level mapping completes on the first run. Custom property names follow HubSpot's camelCase naming convention and appear in the property settings UI.
RETAINUSER CRM
Attachments / files
HubSpot
HubSpot Files
1:1RetainUser file attachments on contacts and deals are downloaded and re-uploaded to HubSpot Files. Each file is reattached to its originating record in HubSpot. File size limits apply — HubSpot supports files up to 25MB per upload. Inline images embedded in notes are extracted, rehosted as HubSpot Files, and the note body is updated with the new image URLs.
RETAINUSER CRM
Pipeline
HubSpot
Pipeline
1:1RetainUser pipelines map directly to HubSpot pipelines. If you have one pipeline in RetainUser, it maps to one pipeline in HubSpot. If you have multiple pipelines in RetainUser (e.g., separate pipelines for buy-side and sell-side deals), each becomes a separate HubSpot pipeline. Stage names are mapped per pipeline — we apply a default mapping and show you the stage value table before migration runs.

Migration approach
Plan HubSpot pipelines, stages, and custom properties before data extraction
FlitStack AI reviews your RetainUser account configuration — contact properties, deal stages, custom fields, pipelines, and owner list — and produces a HubSpot setup plan. This includes the pipeline names and stage definitions to create in HubSpot, the custom properties to create for real-estate-specific fields (property_type, agent_name, listing_date, etc.), and the owner email list to match against HubSpot users. We deliver this plan before any data extraction so your HubSpot account is schema-ready before the first record lands.
Extract RetainUser data via API with validation and deduplication
We pull all contacts, companies, deals, activities, and custom field definitions from RetainUser using the RetainUser API. Extracted records are validated for required fields, format consistency, and duplicate detection. Owner email addresses are extracted for resolution against HubSpot user records. Any records with missing required fields (empty email on a contact, for example) are flagged and surfaced in a pre-migration data quality report so your team can decide how to handle them before the migration runs.
Run a sample migration with field-level diff against a representative data slice
A representative slice of records — typically 100–500 contacts, 50–100 companies, and 50–200 deals spanning multiple pipelines and owners — is migrated to a HubSpot test environment or sandbox. FlitStack generates a field-level diff showing every source value and its destination equivalent. You review lifecycle_stage mapping, deal stage value mapping, owner resolution results, and contact-deal role assignments before the full migration commits. Any mapping adjustments are made to the migration plan before the full run.
Execute full migration with delta-pickup and audit logging
The full dataset migrates to HubSpot with companies landing first, then contacts, then deals with resolved owner assignments and contact-deal role defaults applied. A delta-pickup window of 24–48 hours captures any records created or modified in RetainUser during the cutover window. Every operation is logged in FlitStack's audit log — record counts, transformation notes, skipped records, and owner resolution status. One-click rollback is available if reconciliation against the pre-migration record counts fails.
