Overview
Simply CRM is built on the SugarCRM Professional engine and stores records in a traditional relational model — contacts linked to accounts, deals with stage pick-lists and probability values, and activities logged as separate objects with owner IDs and timestamps. The platform supports custom fields and has a documented REST API for export, though review evidence shows that export output sometimes diverges from what records display inside the application — a discrepancy teams need to account for before migration begins. HubSpot uses a flat properties-bag model for contacts and companies, a separate deals object with configurable pipelines and stage values, and an engagement model for calls, emails, and meetings. HubSpot has no native Lead object; Simply CRM leads route to HubSpot contacts with a lifecycle_stage property that captures progression state. The migration carries contacts, companies, deals, notes, tasks, and custom field data into HubSpot's schema. Simply CRM workflows, automation rules, and assignment logic do not transfer — those must be rebuilt in HubSpot workflows. FlitStack AI sequences the migration to resolve foreign-key dependencies (companies first, then contacts, then deals), runs a sample migration with field-level diff, and captures a delta window during cutover so any in-flight changes in Simply CRM are reflected in HubSpot at go-live.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Simply 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.
Simply CRM
Contact
HubSpot
Contact
1:1Simply CRM contacts map directly to HubSpot contacts. The contact's primary account link resolves to HubSpot's primary company association. Emails, names, phone numbers, job titles, and addresses transfer as HubSpot properties. Owner assignment resolves by email match against HubSpot users.
Simply CRM
Lead
HubSpot
Contact
1:1Simply CRM leads have no direct HubSpot equivalent because HubSpot consolidates leads and contacts into one object. Lead records migrate as HubSpot contacts with a lifecycle_stage property value of 'lead'. Lead status (New, Assigned, Converted) is preserved as a custom property.
Simply CRM
Account
HubSpot
Company
1:1Simply CRM accounts map to HubSpot companies. Company name, domain, industry, employee count, and annual revenue transfer as matching HubSpot company properties. Parent-account hierarchies in Simply CRM map to HubSpot's parent company field if configured. If a parent-account hierarchy exists, the top-level account becomes the primary HubSpot company, and child accounts are linked via the parent‑company association to preserve organizational context.
Simply CRM
Deal
HubSpot
Deal
1:1Simply CRM deals migrate to HubSpot deals with deal name, amount, close date, and stage. Stage values are mapped value-by-value to the corresponding HubSpot pipeline stage name. Probability percentages are stored as a custom field since HubSpot stage probabilities are not exposed as importable properties.
Simply CRM
Pipeline
HubSpot
Deal Pipeline
1:1If Simply CRM uses multiple pipelines (via custom modules or separate modules), each pipeline becomes a separate HubSpot deal pipeline. HubSpot allows multiple pipelines with independent stage sets. The migration plan specifies the pipeline name and stage list before the import runs.
Simply CRM
Call
HubSpot
Engagement (Call)
1:1Simply CRM logged calls transfer as HubSpot call engagement records on the associated contact timeline. Duration, call date, direction (inbound/outbound), and disposition notes migrate as engagement metadata properties. Owner and original timestamp are preserved. Call recordings, if stored in Simply CRM, are downloaded and attached to the HubSpot call engagement as a file link, allowing users to playback directly from the contact record.
Simply CRM
HubSpot
Engagement (Email)
1:1Logged emails in Simply CRM migrate as HubSpot email engagements on the contact timeline. Subject line, body content, timestamp, and associated contact links are preserved. Attachments are downloaded and re-uploaded to HubSpot file storage. Email headers, including the sender and recipient addresses, are captured in HubSpot's engagement metadata to maintain full context for future reference and reporting.
Simply CRM
Meeting
HubSpot
Engagement (Meeting)
1:1Simply CRM meetings (with subject, start/end time, location, and attendees) migrate as HubSpot meeting engagements on the contact timeline. Original meeting start/end timestamps and the meeting title are preserved. Attendee contact links are rebuilt in HubSpot. If a meeting includes external guests without a HubSpot contact record, FlitStack AI creates a placeholder contact to link the meeting, ensuring the engagement timeline remains complete.
Simply CRM
Note
HubSpot
Note
1:1Simply CRM notes transfer as HubSpot contact or company notes with the original body text, author (matched by email to HubSpot user), and creation timestamp. Rich-text formatting is preserved where Simply CRM stores it as HTML. If a note references other records, such as linked deals or tasks, FlitStack AI maps those associations to HubSpot's note-to-record links, maintaining relational integrity across the migrated dataset.
Simply CRM
Task
HubSpot
Task
1:1Open and completed tasks in Simply CRM migrate as HubSpot tasks with subject, due date, status, priority, and associated contact link. Completed tasks are marked done in HubSpot. Uncompleted tasks retain their open status. If a task's assigned user does not have a HubSpot owner record, FlitStack AI flags the task for owner mapping and allows your team to assign a fallback owner before the migration runs.
Simply CRM
Custom Field (Contact)
HubSpot
Contact Property
1:1Simply CRM custom fields on contacts are read from the API and created as HubSpot contact properties before import. Property type is inferred from Simply CRM's field type (text, number, date, picklist). Pick-list custom fields use HubSpot option maps. If a picklist contains values not present in HubSpot's default set, FlitStack AI creates a custom option list and maps each legacy value to the new options, preserving the original data semantics.
Simply CRM
Custom Field (Deal)
HubSpot
Deal Property
1:1Simply CRM custom fields on deals are created as HubSpot deal properties before migration. Number and currency fields transfer directly. Text fields become string properties. Date fields use HubSpot date property type. If a custom field stores a multi-select picklist, FlitStack AI creates a HubSpot checkbox or multi-checkbox property and maps each selected value, ensuring no data loss during the import.
Simply CRM
Document/Attachment
HubSpot
HubSpot File
1:1Simply CRM document attachments associated with contacts, accounts, or deals are downloaded, then uploaded to HubSpot Files. They are linked back to the associated contact or deal record via HubSpot's file-to-record association model. File metadata such as the original upload date, file size, and author information is preserved as HubSpot file properties, enabling accurate recordkeeping and searchability within the platform.

Migration approach
Audit Simply CRM data via API
FlitStack AI connects to your Simply CRM instance via the REST API and pulls a full inventory of records: contact count, account count, deal count, activity volumes, and custom field metadata. This inventory determines the migration scope and identifies any records with null required fields, missing owner assignments, or unusual data patterns that need attention before the migration plan is written.
Create HubSpot properties and pipelines
Before any data moves, FlitStack AI creates the HubSpot contact properties, deal properties, and deal pipelines needed to receive Simply CRM data. Custom fields from Simply CRM are created as HubSpot properties with inferred types. Multi-pipeline Simply CRM setups result in multiple HubSpot pipelines configured with the correct stage names and probability values specified in the mapping plan. Each property is labeled according to the original Simply CRM field name for straightforward identification, and any picklist fields are populated with the appropriate option set before the migration dataset is loaded.
Migrate accounts, then contacts, then deals, then activities
The migration follows a dependency order to preserve relationships: companies first (HubSpot companies must exist before contacts can link to them), contacts second (HubSpot contacts must exist before engagements can attach to them), deals third (deals link to companies), and activities last. Simply CRM leads are processed in the contacts phase with lifecycle_stage assignment applied. FlitStack AI generates a sequencing report before the run so your team can verify the order.
Run sample migration with field-level diff
A representative slice — typically 200–500 records covering contacts, accounts, deals, and several activity types — migrates first. FlitStack AI generates a field-level diff report comparing source values against destination values for every mapped field. Your team reviews the diff to confirm lifecycle_stage assignment, pipeline-to-stage mapping, owner resolution, and custom field population before the full migration is approved. The diff also flags any records with missing required fields, duplicate email addresses, or unresolved owners, giving your team a clear checklist to address before proceeding.
Execute full migration with delta-pickup window
The full migration runs against HubSpot production. A delta-pickup window (typically 24–48 hours) captures any records created or modified in Simply CRM during the cutover period. All operations are logged in the audit trail. If reconciliation fails — a record count mismatch, missing associations, or duplicate detection — FlitStack AI provides a one-click rollback plan that reverts the HubSpot environment to its pre-migration state while your team resolves the issue.
