Overview
Basic Online CRM stores data in a flat, contact-centric model with basic company records, simple deal tracking, and limited custom field support. HubSpot's CRM uses a richer object graph with Contacts, Companies, Deals, Tickets, and optional Custom Objects — plus HubSpot's signature lifecycle_stage property that tracks leads from first touch through customer and beyond. This migration carries everything Basic Online CRM holds natively — contacts, companies, deals, notes, tasks, and any custom fields — into HubSpot's structured object model. The primary translation work is mapping Basic Online CRM's basic pipeline stages to HubSpot's deal pipelines and stages, converting any custom fields to HubSpot custom properties, and resolving owner email addresses against HubSpot user accounts. HubSpot's marketing-contact billing flag has no equivalent in Basic Online CRM, so that concept is new in HubSpot and will require your team to set the flag manually post-migration or through a workflow. FlitStack AI uses HubSpot's native import API for contacts and companies, the bulk import tool for deals, and preserves all association links between records. The migration runs in read-only mode against Basic Online CRM, so your team keeps working throughout the process.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Basic Online 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.
Basic Online CRM
Contact
HubSpot
Contact
1:1Basic Online CRM contact records map 1:1 to HubSpot Contacts with all standard fields transferring as HubSpot native properties including name, email, phone, and address fields. The original create date from Basic Online CRM is preserved in HubSpot's original_create_date custom property for historical continuity in reports. Contacts without email addresses are flagged for manual review since HubSpot requires email for most automation triggers and workflow enrollments.
Basic Online CRM
Company
HubSpot
Company
1:1Basic Online CRM company and organization records map directly to HubSpot Companies, preserving company names, domains, industry classifications, employee counts, and annual revenue data. Parent-child company hierarchies in Basic Online CRM map to HubSpot's Parent Company association property, maintaining organizational structures through the migration. All company address information transfers to HubSpot's corresponding address properties on the company record.
Basic Online CRM
Deal
HubSpot
Deal
1:1Basic Online CRM deals map to HubSpot Deals with the deal name, amount, close date, and owner transferring directly to HubSpot deal properties. Deal stage names in Basic Online CRM map to HubSpot pipeline stages based on the pipeline configuration. If Basic Online CRM has multiple pipelines, each becomes a separate HubSpot pipeline with its own dedicated stage set during the migration.
Basic Online CRM
Pipeline
HubSpot
Deal Pipeline
1:1If Basic Online CRM supports multiple sales pipelines, each pipeline becomes a named HubSpot Deal Pipeline. HubSpot pipelines are created in Settings > Deals > Pipelines before data loads. Stage order and probability weights are configured per pipeline in HubSpot.
Basic Online CRM
Task
HubSpot
Task (Engagement)
1:1Basic Online CRM tasks map to HubSpot Tasks which appear in the contact timeline as engagement records with subject, due date, status, and owner information transferred. Completed tasks retain their completion timestamp in HubSpot's activity log, preserving the full task history for compliance and reference purposes. Task associations to contacts carry over as engagement links in HubSpot's timeline view.
Basic Online CRM
Note
HubSpot
Note (Engagement)
1:1Basic Online CRM notes map to HubSpot Notes attached to the corresponding contact or company record. Note body text transfers in full. If notes contain @mentions or internal flags, those are preserved as plain text since HubSpot Notes have no permission-scoped visibility.
Basic Online CRM
Activity Log
HubSpot
Call / Email / Meeting
1:manyBasic Online CRM engagement logs that distinguish activity type by category such as calls, emails, or meetings are split into HubSpot's respective engagement objects during migration. Calls become HubSpot Calls with duration and direction preserved, emails become HubSpot Email engagements, and meetings become HubSpot Meeting records — each retaining original timestamps and owner attribution from the source system.
Basic Online CRM
Custom Field (Contact)
HubSpot
Custom Property (Contact)
1:1Basic Online CRM custom fields on contacts create HubSpot custom properties. Text fields map to HubSpot single-line text or multiple-line text properties. Number fields map to HubSpot number properties. Date fields map to HubSpot date properties. Pick-list values map to HubSpot select or radio button properties.
Basic Online CRM
Custom Field (Deal)
HubSpot
Custom Property (Deal)
1:1Basic Online CRM custom fields on deals create HubSpot custom deal properties. Each custom property is created in HubSpot Settings > Properties before migration so the import tool recognizes the destination field. Properties are scoped to the Deals object only.
Basic Online CRM
User / Owner
HubSpot
User (by email)
1:1Basic Online CRM owner/user assignments resolve by email match against HubSpot Users. Unmatched owners are flagged pre-migration — your team either creates the HubSpot user first or assigns those records to a fallback owner. No record lands without a valid HubSpot owner.
Basic Online CRM
Attachment
HubSpot
File (HubSpot CRM Files)
1:1Basic Online CRM file attachments associated with contacts or deals are downloaded and re-uploaded to HubSpot CRM Files. Files attach to the corresponding HubSpot record via the Files tool. HubSpot's file storage limits apply — Starter includes 10GB, Professional and Enterprise include more.
Basic Online CRM
Product / Line Item
HubSpot
Product + Line Item
1:1If Basic Online CRM tracks products linked to deals, those map to HubSpot Products and Line Items. Products are created first in HubSpot (name, SKU, price), then line items are created per deal linking the product. Basic Online CRM product data without SKU/pricing may require manual cleanup before mapping.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Basic Online CRM gotchas
CSV export silently truncates large contact lists
Deal-Contact associations are stored by internal ID only
Custom field data types are not preserved on export
No native attachment storage means files are not migrated
User/owner structure is not explicit in exported data
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Audit Basic Online CRM data model and export structure
FlitStack AI connects to Basic Online CRM via read-only API access and audits the full data model — standard objects, custom fields, activity history volume, and association links between contacts, companies, and deals. We export sample records from each object to verify field format (date formats, pick-list values, empty field handling) and identify any non-standard data that requires transformation before HubSpot import. This audit produces the migration scope document and a field-mapping spreadsheet that your team reviews before any data moves.
Pre-create HubSpot custom properties and pipelines
Based on the audit, FlitStack AI generates a HubSpot setup checklist: custom properties to create per object, pipeline names and stages to configure, and any value-mapping tables for pick-list fields. Your HubSpot admin creates these in the destination portal before migration — or our team creates them using HubSpot's API with your permission. No import can run until the destination schema matches the mapping plan. We validate the schema match before proceeding to extraction.
Resolve owner email matches against HubSpot users
Basic Online CRM owner IDs resolve by email against HubSpot User accounts. FlitStack AI generates an owner resolution report listing every unique owner in Basic Online CRM, their email, and their HubSpot user match status. Green rows indicate a match; red rows indicate an owner with no HubSpot user account. Your team creates HubSpot accounts for unmatched owners or assigns a fallback owner before migration. No record imports without a valid HubSpot owner ID — this prevents orphaned records with no accountability in HubSpot.
Run sample migration with field-level diff
A representative slice — typically 100–300 records spanning contacts, companies, deals, and activities — migrates first into a HubSpot test portal or a dedicated test pipeline. FlitStack AI generates a field-level diff comparing source values to destination values so you can verify every mapping. You review the diff and confirm lifecycle stage handling, pipeline routing, owner resolution, and custom field population before the full run commits. Adjustments to the mapping plan happen at this stage without touching live data.
Execute full migration with delta-pickup window
Full data migration runs against the production HubSpot portal. Companies and contacts migrate first (since deals depend on them), followed by deals with their company and contact associations, then activity history. During the migration, your team continues working in Basic Online CRM — FlitStack AI uses scoped read-only access and does not modify the source. A 24–48 hour delta-pickup window after the main run captures any records created or modified in Basic Online CRM during the migration window. Audit log records every operation; rollback is available if reconciliation identifies unexpected gaps.
