When the Move Makes Sense
Salesforce-to-HubSpot is not a downgrade and not a universal answer. It is the right move when your team has outgrown the maintenance cost of Salesforce relative to the value you extract from it. The clearest signal: you are paying for licenses, an admin, and an integration partner just to keep the org running, while sales reps still log into spreadsheets.
We have run this migration for SaaS companies under 200 employees, services firms with PLG motions, and HubSpot Marketing customers who want one unified CRM. The playbook below is what consistently works.
Phase 1: Data Model Audit
Before any data moves, you map both systems side by side. The question is not how to move every Salesforce field - it is which fields actually drive decisions today and which are debris.
- Inventory every custom object, custom field, validation rule, workflow, and process in Salesforce.
- Tag each item: in active use (last 90 days), referenced by reports, or legacy debris.
- Map active items to HubSpot equivalents: standard objects, custom objects, custom properties, workflows.
- Flag what does not fit cleanly (complex many-to-many relationships, heavy Apex logic, multi-step approvals) - these are the cases where you either restructure on HubSpot or keep on Salesforce.
Typical mid-market Salesforce orgs have 200-400 custom fields. The migration usually carries 60-80 of them. The rest die in the audit, and nobody misses them.
Phase 2: HubSpot Architecture
Designing the HubSpot org is the highest-leverage part of the project. Decisions made here cost months to undo later.
- Object model: which Salesforce custom objects become HubSpot custom objects vs. properties on standard objects.
- Pipeline model: deal stages, ticket pipelines, and any custom record pipelines.
- Property dictionary: a shared definition of every property so reporting stays consistent across teams.
- Permission model: teams, partitions, field-level rules - mapped to your Salesforce profiles and sharing rules.
- Workflow patterns: which Salesforce flows become HubSpot workflows, which become Operations Hub programmable workflows.
Phase 3: Integration Map
Salesforce rarely lives alone. Before migration, you need a clear view of every integration touching the CRM.
- Inbound: marketing automation, web forms, lead enrichment, support ticket sources.
- Outbound: data warehouse, billing system, customer support tool, BI tool, finance system.
- Bidirectional: marketing platform, customer success tool, e-signature, CPQ.
Every integration either gets rebuilt against HubSpot APIs, replaced with a HubSpot-native equivalent, or kept on Salesforce in a hybrid model. Plan this before data migration starts, not after.
Phase 4: Data Migration
Data migration breaks down into three substreams that run in parallel:
- Master data: companies, contacts, deals, custom objects. Migrated in batches, validated against record counts and spot checks before each batch.
- Historical activity: emails, calls, meetings, notes. Critical for sales context but voluminous - typical migrations carry 2-3 years and archive older activity to S3 or BigQuery.
- Attachments and documents: files, signed contracts, custom Lightning components storing data. Usually moved separately via the HubSpot Files API.
We run a 4-week parallel period where both systems are live. Sales reps continue working in Salesforce while data flows to HubSpot. This catches schema gaps, validation errors, and edge cases before cutover.
Phase 5: Cutover and Stabilization
Cutover is the moment Salesforce becomes read-only and HubSpot becomes the source of truth. It is also when the project either holds together or falls apart.
- Final delta migration of records changed in the last 24 hours.
- Reconciliation report - record counts, sum of deal amounts, key custom property completeness - signed off by sales and ops leadership.
- Salesforce becomes read-only for 30 days as a rollback option, then archived.
- 30-day hypercare with daily standups, weekly sales rep office hours, and rapid-response fixes for whatever surfaces in production.
What Goes Wrong
Three failure modes we see in migrations we did not run:
- Trying to recreate Salesforce in HubSpot 1:1. The migration is the chance to clean up - take it. Carrying every old validation rule defeats the point.
- Skipping the parallel-run. Cutover-without-parallel migrations regularly discover bad data or missing integrations the day after go-live, when sales reps are already on the new system.
- Treating sales enablement as a week-one training session. Adoption requires office hours, recorded walkthroughs, and at least 60 days of in-context support before reps trust the new system.
Done well, a Salesforce-to-HubSpot migration ships in 10-16 weeks for mid-market orgs. The reduction in licensing, admin time, and integration debt typically pays back inside a year.
