Overview
Teams migrate from Lemon Tech to HubSpot CRM when they need a unified platform that connects marketing, sales, and service without requiring multiple disconnected tools. The migration carries everything Lemon Tech stores natively — contacts, companies, deals, activities, and custom fields — into HubSpot's object model with its association-based contact-to-company graph and lifecycle stage tracking. The migration mechanism uses HubSpot's native Contacts API and Companies API for standard records, with bulk import for large datasets exceeding API throughput limits. The harder problems are mapping any custom fields from Lemon Tech into HubSpot's custom property schema, preserving deal pipeline stage history as HubSpot deal stages, and resolving owner records by email match against HubSpot user accounts. FlitStack AI sequences the migration so foreign-key dependencies resolve correctly — companies land first, then contacts with their primary company associations, then deals with owner and contact role links. Activity history (calls, emails, meetings, notes) migrates as engagement records attached to the parent contact. Workflows, sequences, and automation logic in Lemon Tech do not transfer — those require a separate rebuild in HubSpot's workflow builder, and FlitStack provides an export of workflow definitions to support that rebuild.

Object mapping
Each row shows how a Lemon Tech 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.
Lemon Tech
Contact / Person
HubSpot
Contact
1:1Lemon Tech person records map directly to HubSpot contacts. The primary company association in Lemon Tech becomes the HubSpot contact's primary company association. Multiple company associations require HubSpot's association model — the primary company is mapped first, secondary associations are created as additional company links.
Lemon Tech
Company / Account
HubSpot
Company
1:1Lemon Tech company records map 1:1 to HubSpot companies. Company hierarchies (parent/child relationships) in Lemon Tech preserve as HubSpot parent company associations. Domain-based company matching in HubSpot is enabled post-migration for automatic duplicate detection on new imports. Additional fields such as industry classification, employee count, and address details migrate directly, and any custom properties on the company object are created in HubSpot before import to ensure schema consistency.
Lemon Tech
Deal / Opportunity
HubSpot
Deal
1:1Lemon Tech deal records map to HubSpot deals with deal name, amount, close date, and stage migrated. Each Lemon Tech pipeline maps to a HubSpot deal pipeline. Stage values map to HubSpot deal stages by name with probability weights re-applied from HubSpot's stage configuration.
Lemon Tech
Pipeline
HubSpot
Deal Pipeline
1:1Lemon Tech pipelines become HubSpot deal pipelines. HubSpot allows multiple pipelines per portal, and each pipeline has its own set of stages with custom probability and forecast settings. Pipeline-level settings from Lemon Tech (if configurable) migrate as pipeline metadata attached to the HubSpot pipeline configuration.
Lemon Tech
Activity (Call / Email / Meeting)
HubSpot
Engagement (calls, emails, meetings)
1:1Lemon Tech engagement records (calls, emails, meetings) map to HubSpot engagement records attached to parent contact. Timestamps, owners, and body content are preserved. HubSpot's engagement timeline displays these activities chronologically on each contact record. Each activity type uses its corresponding HubSpot engagement type, and attachments are referenced by URL after re‑uploading to HubSpot Files. For large volumes, FlitStack uses HubSpot's bulk import to respect API rate limits while maintaining fidelity.
Lemon Tech
Note
HubSpot
Engagement: Note
1:1Lemon Tech notes migrate as HubSpot engagement notes attached to parent contact or company. Rich-text formatting in Lemon Tech notes is preserved as HTML within HubSpot's note body. Timestamp and owner attribution migrate for audit continuity. If notes contain inline images, FlitStack extracts the files, re-uploads them to HubSpot Files, and updates image URLs in the HTML to point to the new locations, preserving visual integrity.
Lemon Tech
Owner / User
HubSpot
User (Owner)
1:1Lemon Tech owner records are resolved by email match against HubSpot user accounts. FlitStack AI performs an email lookup against HubSpot's user directory before migration. Records with unmatched owner emails are flagged and assigned to a designated fallback owner specified by the customer.
Lemon Tech
Custom Field / Custom Property
HubSpot
Custom Property
1:1Lemon Tech custom fields on any object become HubSpot custom properties on the equivalent object. FlitStack AI creates the custom property in HubSpot with the appropriate field type (string, number, date, checkbox, picklist) before migrating data. Picklist fields require value-by-value mapping if Lemon Tech uses custom picklist values.
Lemon Tech
Custom Entity
HubSpot
Custom Object
1:1Lemon Tech custom entities map to HubSpot custom objects (available on HubSpot Professional and Enterprise tiers). Custom entity associations that use N:N relationships in Lemon Tech require HubSpot custom relationship definitions. FlitStack maps the association schema and validates relationship integrity post-migration.
Lemon Tech
Attachment / File
HubSpot
Files
1:1Lemon Tech file attachments on records re-upload to HubSpot Files and are linked back to the parent record. File size limits apply per HubSpot's file storage configuration (25MB per file). Inline images in notes are extracted, rehosted, and the reference URLs are updated in the note body.
Lemon Tech
Lifecycle Stage
HubSpot
Lifecycle Stage (contact property)
1:1If Lemon Tech tracks a lifecycle or status property on contacts, that value maps to HubSpot's lifecycle_stage property by value. Lemon Tech records without a lifecycle value default to 'lead' in HubSpot. Customers can override this default mapping during the planning phase.
Lemon Tech
Lead Status
HubSpot
Lead Status (contact property)
1:1Lemon Tech lead status values map to HubSpot's hs_lead_status property. Custom status labels in Lemon Tech require explicit value-by-value mapping against HubSpot's lead status pick-list options. Status history (timestamps) is preserved as a custom datetime property for reporting continuity. During migration, FlitStack validates that each mapped status value exists in HubSpot's pick-list; any missing values are flagged for customer review before the import runs to avoid data rejection.

Migration approach
Audit Lemon Tech data model and map to HubSpot schema
FlitStack AI ingests the Lemon Tech data export (API pull or database backup) and catalogs all objects, fields, custom entities, and association types. We produce a field-level mapping spreadsheet that pairs each Lemon Tech field with its HubSpot equivalent, noting which fields require custom property creation in HubSpot. This mapping document is reviewed and approved by the customer's HubSpot admin before migration proceeds. The audit also identifies data quality issues (duplicate records, missing required fields, malformed values) that require cleaning before import.
Resolve owners by email match against HubSpot users
Before any records migrate, FlitStack AI performs an owner resolution pass. Each Lemon Tech owner record is matched against HubSpot user accounts by email address. Records with matched owners receive the correct HubSpot owner ID. Records with unmatched owners are flagged and held in a quarantine list. The customer specifies a fallback owner (or chooses to invite the unmatched users to HubSpot before migration). No contact or deal migrates without a resolved owner unless explicitly approved by the customer during the planning phase.
Migrate companies first, then contacts, then deals with dependency ordering
HubSpot requires company records to exist before contacts can associate to them (via the primary_company association). FlitStack sequences the migration to satisfy foreign-key dependencies: companies land first, contacts follow with their primary company link resolved, and deals migrate last with owner ID and deal-contact associations resolved. This sequencing ensures that HubSpot's referential integrity checks pass during import and that HubSpot's company-contact counts and deal rollup calculations reflect the correct data immediately after migration.
Run a sample migration with field-level diff before full run
FlitStack AI executes a representative sample migration — typically 100–500 records spanning contacts, companies, deals, and a sample of activity records — before committing the full dataset. The sample run generates a field-level diff report comparing source values against destination values for every mapped field. Customers review the diff to verify that lifecycle stage mapping, deal stage mapping, owner resolution, and association labels are correct. Approval of the sample diff is required before the full migration run is scheduled.
Execute full migration with delta-pickup window and audit log
The full migration runs against the live HubSpot portal using the approved mapping. A delta-pickup window (typically 24–48 hours) runs concurrently, capturing any records created or modified in Lemon Tech during the cutover period. FlitStack AI generates a full audit log of every record created, updated, or skipped, with source ID, destination ID, and operation timestamp. One-click rollback is available if reconciliation fails or if the customer identifies a mapping error in the first 24 hours post-migration. Rollback restores the destination to its pre-migration state and triggers a re-run with corrected mapping.
