Data migration is a standard component of most HubSpot implementation projects, covering contacts, companies, deals, tickets, and historical activity records. Whether it is included depends on the project scope, but agencies typically offer it as either a bundled deliverable or a separate workstream.
Migration involves several steps: auditing the source system's data quality, mapping fields between the old CRM and HubSpot, deduplicating records, standardizing formats, running test imports on small datasets, and validating the full migration before cutover. Lean Labs offers HubSpot migrations as a distinct service tier starting at $7,000, covering contacts, workflows, and workstreams from another CRM. One client case study describes a migration completed one day ahead of a 30-day timeline, with marketing assets rebuilt during the process. The complexity scales with data volume, the number of custom objects, and how many integrations connect to the source CRM. Salesforce migrations add specific challenges because Salesforce uses a separate Leads object that maps differently to HubSpot's contact model.
