CRM data migration is one of those projects that looks simple on paper—export, map, import—but can derail revenue if you skip the details. In 2025, teams succeed by treating CRM migration like an operational changeover, not just a CSV exercise: audit what you have, decide what to move (and what to retire), build a repeatable pipeline, and practice cutover until it’s boring. This guide gives you a human, battle-tested plan to migrate CRM data with near-zero downtime and clean records on day one.
Move fast without breaking relationships: audit → map → test → cut over → hypercare.
CRM data migration: what it is and why it matters
CRM data migration is the process of moving contacts, companies, deals, activities, custom fields, and automation context from one CRM to another (or to a new instance). Done right, sellers log in on Monday and keep working—with better data, faster UI, and no missing history. Done poorly, you lose pipeline visibility, automations misfire, and trust in the CRM evaporates.
Primary goal: preserve data integrity and sales momentum.
Secondary goal: reduce tech debt—archive stale fields, normalize picklists, and fix duplicates.
Hidden goal: align data to your 2025 motion (ICP, lifecycle, attribution), not just “lift and shift.”
Map it once, use it everywhere: a clear matrix powers repeatable loads and tests.
Migration strategies: big bang vs phased vs parallel
Big bang: complete cutover over a weekend. Pros: fast; Cons: high risk if test coverage is weak.
Phased by team/region: migrate one motion at a time. Pros: contained risk; Cons: cross‑system coordination.
Parallel run: sync data bi‑directionally for 2–4 weeks. Pros: safest; Cons: more tooling and governance.
Recommendation for 2025: parallel or phased where possible. Use a one‑way nightly sync early, then bi‑directional for a short stabilization period before final cutover.
Tools and methods (choose the right path)
Native importers: quick for CSVs; best for contacts/companies. Verify limits and object dependencies.
APIs/webhooks: precise control, better for activities/notes and preserving relationships.
iPaaS (Zapier/Make/n8n): good for incremental sync and light transforms.
Bespoke scripts: Node/Python with SDKs for complex workflows and idempotency.
Managed vendors: specialized migration partners when scope is large or regulated.
Sanitization: securely delete staging copies per policy after validation is complete.
Example migration playbooks (high‑level)
Salesforce → New CRM: Use Data Export or API to pull Accounts, Contacts, Opportunities, Tasks, Events. Preserve IDs in an externalId column; import to target in dependency order. Rebuild pipelines, validation rules, and page layouts first.
HubSpot → New CRM: Export objects via HubSpot export tools; include associations file. Maintain lifecycle stage mapping; re‑implement workflows after data loads.
Zoho CRM → New CRM: Export modules with IDs; check picklists and multi‑select formats; test attachments and notes import paths.
Dynamics 365 → New CRM: Use Data Export Service or APIs; verify owner/team mappings and currency conversions.
Always verify current steps in official documentation before you run production imports (links below).
Common pitfalls (and quick fixes)
Automations firing on import: quarantine workflows or add an “Import” flag to suppress sequences.
Owner mismatches: pre‑create users; map by email; set a fallback owner for orphans.

Frequently asked questions
How long does a CRM data migration usually take?
Small teams can complete in 2–4 weeks; larger orgs with custom objects and integrations should expect 6–10 weeks including rehearsal and hypercare.
What should I migrate vs archive?
Migrate active contacts, current pipeline, last 12–24 months of activity, and required custom fields. Archive stale fields, deprecated stages, and historical logs you won’t use.
How do I prevent automations from firing on import?
Disable or scope workflows to exclude records with an “Import” flag/tag and date window. Re‑enable after cutover.
What order should I import objects?
Accounts/companies first, then contacts, products, deals/opportunities, followed by tasks/events/notes, tickets, and custom objects.
How do I handle duplicates?
Deduplicate in source before export and enforce duplicate rules in target. Normalize keys (email, domain) and run a post‑import dedupe pass.
Can I run both CRMs in parallel?
Yes. Use a one‑way sync initially, then short bi‑directional sync for 1–2 weeks to reduce risk. Document the “system of record” during parallel.
How do I preserve activity history?
Export tasks/events/notes via API where possible; many native importers don’t support activity relationships. Maintain external IDs to re‑link.
What’s the biggest hidden risk?
Field mapping drift. Lock picklists and validations early, and test with real edge cases (international addresses, multi‑currency, custom stages).
How do I verify success post‑cutover?
Match record counts, recreate key dashboards, run user spot checks, and monitor pipeline integrity and adoption for 14 days.
Where do I verify vendor‑specific steps?
Always review and follow the latest official documentation for your source and target CRMs before running production imports.
