HubSpot Data Migration Playbook

The problem

CRM migrations fail quietly. You finish the import only to realize weeks later that associations dropped, duplicates flooded the database, or deal history mapped to the wrong pipeline stages.

What it does

• Enforces a strict dependency-ordered import sequence (Companies/Contacts before Deals) to maintain data integrity.
• Standardizes source-side deduplication by domain and email to prevent messy post-migration cleanups.
• Implements mandatory external ID tagging and migration run IDs for idempotent retries and easy rollbacks.
• Defines a formal validation framework including count parity, association integrity checks, and stage distribution audits.

Why this beats prompting it yourself

General LLMs often suggest simple CSV uploads that ignore HubSpot API batch ordering and association dependencies. This skill builds in specific safeguards like external ID mapping and post-migration spot-checking protocols that prevent silent data loss.

Use cases

• Migrating a client from Salesforce or Pipedrive into HubSpot.
• Merging two separate HubSpot portals after a company acquisition.
• Restructuring a messy CRM by exporting, cleaning, and re-importing data.

Known limitations

Does not cover migration of attachments, email history, or call logs. Custom object migrations require a finalized schema before using this playbook.
