HubSpot Migration from Salesforce: Plan, Data & Cutover (2026)
Step-by-step HubSpot migration from Salesforce: data mapping, custom objects, contacts and deals, cutover plan, and post-migration automation.

HubSpot Migration from Salesforce: Plan, Data & Cutover (2026)
Migrating from Salesforce to HubSpot is a major change. Done well, you gain a single platform for marketing and sales; done poorly, you risk lost data, confused teams, and stalled pipeline.
This guide walks through how to plan and execute a HubSpot migration from Salesforce: data mapping, contacts and deals, custom objects, cutover, and post-go-live automation so nothing falls through the cracks.
Why Companies Move From Salesforce to HubSpot
Common drivers:
- Unify marketing and sales: One CRM for leads, contacts, deals, and marketing automation instead of Salesforce + separate tools.
- Ease of use: Teams adopt HubSpot faster; less dependency on admins for simple changes.
- Cost: For mid-market, HubSpot can be simpler and cheaper than Salesforce + Marketing Cloud + integrations.
- Growth stack: Lead generation, paid ads, and content in one place.

Migration Principles
- Clean first: Dedupe and fix data in Salesforce before migrating.
- Map everything: Field-by-field mapping (Salesforce → HubSpot).
- Phased where possible: Migrate in order (e.g. contacts → companies → deals → activities).
- Validate: Spot-checks and reports after each phase.
- Train and document: So the team uses HubSpot correctly from day one.
Phase 1: Discovery and Mapping
What to Migrate
- Contacts: Owner, lifecycle stage, lead source, custom fields.
- Companies: Name, domain, industry, size, custom fields.
- Deals: Amount, stage, close date, pipeline, custom fields.
- Activities: Calls, emails, meetings (where possible; often summarized rather than full history).
- Custom objects: Map to HubSpot custom objects or standard objects if they fit.
Field Mapping
Build a spreadsheet: Salesforce object → Salesforce field → HubSpot object → HubSpot property. Note:
- Default fields (name, email, etc.) map 1:1.
- Picklists may need value mapping (e.g. Salesforce “Stage 1” → HubSpot “Appointment scheduled”).
- Some Salesforce fields may have no HubSpot equivalent; decide “drop” or “custom property.”
Data Quality
- Deduplicate contacts and companies (merge or delete).
- Fix invalid emails and required fields.
- Archive or exclude old/irrelevant records if you don’t need them in HubSpot.
Phase 2: HubSpot Setup Before Migration
- Create HubSpot account and set up users, teams, and permissions.
- Create custom properties to match your mapping.
- Configure pipelines (sales, maybe marketing) and deal stages.
- Set up automation basics (e.g. lead assignment) that will apply to migrated data.
- Don’t go live with marketing workflows until after cutover and validation.
Phase 3: Migration Execution
Order of Migration
- Companies (if you use them), then Contacts (with company association).
- Deals (with contact and company association).
- Activities (if you’re importing; often limited).
- Custom objects (if any).
Tools
- HubSpot import: CSV import for contacts, companies, deals.
- Integrations: HubSpot’s Salesforce sync (read-only or limited) or third-party ETL (e.g. Zapier, custom script) for ongoing or one-time sync.
- Manual + CSV: Export from Salesforce, transform (mapping, formatting), import into HubSpot. Validate row counts and key fields.
Cutover
- Choose a low-activity window (e.g. weekend).
- Final export from Salesforce; run migration; validate in HubSpot.
- Switch processes to HubSpot: stop creating new records in Salesforce, start in HubSpot.
- Keep Salesforce read-only for a period so you can reference old data if needed.
Phase 4: Post-Migration
- Re-point integrations: Paid ads, forms, marketing automation, and lead generation tools to HubSpot.
- Workflows: Turn on HubSpot automation (lead routing, nurture, deal updates).
- Training: How to log activities, update deals, use CRM for pipeline.
- Reporting: Recreate key reports in HubSpot; compare to last month in Salesforce for sanity check.
Common Migration Mistakes
- No cleanup: Migrating duplicates and bad data.
- Incomplete mapping: Missing custom fields or pipelines.
- Big-bang cutover without validation: Finding errors only after go-live.
- No rollback plan: What to do if critical data is wrong.
- Skipping training: Adoption suffers and data quality drops.
