Overview
AddressTwo stores contacts, companies, and activities in a flat, relationship-light model designed for small teams. HubSpot uses a linked object graph — Contacts belong to Companies, Deals associate with Contacts via roles, and a lifecycle_stage property tracks prospect progression. The migration maps AddressTwo contacts to HubSpot Contacts, AddressTwo companies to HubSpot Companies, and AddressTwo activity records (calls, emails, notes, tasks) to HubSpot Engagements. AddressTwo's custom fields become HubSpot custom properties, created during the schema-prep phase. AddressTwo workflows and automations do not transfer — they must be rebuilt in HubSpot using Workflows and Sequences. The migration uses AddressTwo's API export and HubSpot's native import API with field-level validation before committing the full dataset. Delta-pickup captures any records modified during the cutover window. During schema preparation, each custom property is defined in HubSpot with the appropriate field type to accept AddressTwo data without rejection. Owner assignments map by email, ensuring the original record custodian appears in HubSpot. The migration sequence loads Companies first, then Contacts, then Deals and Engagements, preserving referential integrity. Post‑import, a delta‑capture window syncs any changes made in AddressTwo while the import runs, keeping the final HubSpot state consistent with the source.

Object mapping
Each row shows how a AddressTwo 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.
AddressTwo
Contact
HubSpot
Contact
1:1AddressTwo contacts map directly to HubSpot Contacts. The contact's primary company in AddressTwo becomes a HubSpot Company lookup (via domain match or company name). If AddressTwo stores company as free text, a HubSpot Company record is created first. All core properties such as first name, last name, email, phone, and address map directly. Any missing required fields are flagged for manual review before import.
AddressTwo
Company
HubSpot
Company
1:1AddressTwo company records map to HubSpot Companies. HubSpot Company Website, Industry, Phone, and Address fields receive AddressTwo's equivalent properties. Parent-company relationships in AddressTwo map to HubSpot's parent_company_id field. If AddressTwo records include a website URL, it populates the HubSpot Company domain field, enabling automatic contact‑company association via domain matching.
AddressTwo
Task / Activity
HubSpot
Engagement (Call, Email, Meeting, Note)
1:1AddressTwo tasks and dated activities map to HubSpot Engagements. Call tasks become HubSpot Call engagements; email tasks become Email engagements; meeting records become Meeting engagements. Original timestamps and assigned owner preserved. Each engagement preserves the original creation timestamp and the owner ID, allowing accurate activity history reconstruction in HubSpot.
AddressTwo
Note
HubSpot
Engagement (Note)
1:1AddressTwo notes migrate as HubSpot Notes attached to the corresponding Contact or Company record. HubSpot stores notes with body text, author, and create date. Large notes may require text truncation during import. The note body is stored as a string in HubSpot; any HTML formatting is stripped to plain text to ensure compatibility with HubSpot's note viewer.
AddressTwo
Custom Field (Contact-level)
HubSpot
Custom Property (Contact)
1:1AddressTwo stores custom key-value pairs on contact records. These require HubSpot custom properties pre-created in HubSpot Settings before import. Field type mapping (text, number, date, checkbox) must be specified per field during planning. During the schema‑prep phase, each custom property receives a type (text, number, date, or checkbox) that matches the source data format to avoid import errors.
AddressTwo
Custom Field (Company-level)
HubSpot
Custom Property (Company)
1:1AddressTwo company custom fields map to HubSpot Company custom properties. Same pre-creation requirement applies. If AddressTwo stores industry classifications as custom picklists, those become HubSpot dropdown properties with the same value options. If the AddressTwo picklist contains values not present in HubSpot's default industry list, new dropdown options are created in HubSpot to preserve the original classification.
AddressTwo
Pipeline / Deal
HubSpot
Deal + Pipeline
many:1AddressTwo deals have stage and amount fields but no multi-pipeline model. All AddressTwo deals migrate into a single HubSpot Deal pipeline. If AddressTwo tracks multiple deal stages, they map to HubSpot Pipeline stages with probability values set per stage name.
AddressTwo
Owner / User
HubSpot
Owner
1:1AddressTwo users resolve to HubSpot Owners by email address match. If an AddressTwo owner has no matching HubSpot user, records assign to a fallback HubSpot owner or remain unassigned pending your admin's instruction. Owner resolution runs before data import. The resolution process runs as a pre‑import step, and any unresolved owners are logged for manual assignment after the data load.
AddressTwo
Attachment / File
HubSpot
File
1:1AddressTwo file attachments download and re-upload to HubSpot Files, attached to the corresponding Contact, Company, or Deal record. HubSpot's file size limit (25MB per file) applies to oversized attachments. Files larger than 25MB are flagged during the inventory phase; they can be split into smaller chunks or archived to an external URL referenced in the HubSpot record.
AddressTwo
Workflow / Automation
HubSpot
Workflow / Sequence
1:1AddressTwo workflows and automated rules do not transfer. They must be rebuilt in HubSpot using Workflows (for CRM automation) and Sequences (for outbound email). FlitStack exports AddressTwo workflow definitions as a reference document for your HubSpot admin. The exported reference document lists each workflow’s trigger conditions, actions, and any dependent custom fields to guide the HubSpot admin during rebuilding.

Migration approach
Export AddressTwo data via API and inventory schema
FlitStack connects to AddressTwo's API using your provided credentials and exports all contacts, companies, activities, and custom field definitions. We inventory the full schema — counting custom fields per object, noting field types, and identifying any relationship metadata AddressTwo stores. This export runs read-only and does not alter your AddressTwo account. The inventory feeds the HubSpot custom property creation checklist and field mapping plan.
Create HubSpot custom properties and pipeline schema
Before data moves, FlitStack generates a step-by-step checklist for creating HubSpot custom properties to match AddressTwo's custom field inventory. Your HubSpot admin (or our team) creates these properties in HubSpot Settings, specifying field types that match AddressTwo's data. We also define the HubSpot pipeline and stage names into which AddressTwo deals will import. This schema-prep phase prevents import API rejections during the data load.
Match owners and create Company records before contacts
HubSpot requires Companies to exist before Contacts can link to them via associatedcompanyid. FlitStack first deduplicates AddressTwo company names into HubSpot Companies, resolving naming inconsistencies (e.g., 'Acme Corp' vs 'Acme Corporation'). Owner matching runs concurrently — AddressTwo user emails resolve to HubSpot user IDs. Unmatched owners flag for your admin's assignment before migration commits. This sequencing ensures foreign keys resolve correctly on import.
Run sample migration with field-level diff
A representative slice — typically 200–500 records across contacts, companies, and activities — imports into your HubSpot staging environment. FlitStack generates a field-level diff comparing source AddressTwo values against destination HubSpot values for every mapped field. Your team reviews the diff to verify company linking, owner assignment, custom property mapping, and activity attachment. Approval of the sample triggers the full migration run. Any field mapping errors discovered during sample migration are corrected before the full commit.
Execute full migration with delta-pickup window
The full dataset imports into HubSpot Production. AddressTwo remains fully operational during import — your team continues working in AddressTwo with no access restrictions. A delta-pickup window (typically 24–48 hours) captures any new or modified records created in AddressTwo during the migration run. FlitStack generates an audit log of every imported record, the source AddressTwo ID, and the resulting HubSpot ID. One-click rollback is available if reconciliation against AddressTwo's post-delta snapshot reveals discrepancies.
