A CRM migration should move useful operational history into a cleaner target model, not copy every field from the old system. Inventory sources, remove duplicates, map records and relationships, test a representative sample, validate counts and ownership, then cut over with a clear freeze and rollback plan.
- Migrate what is useful, not everything available.
- Clean and map before import.
- Test relationships, not just row counts.
- Assign owners for cutover and validation.
Inventory and classify the source data
List every source that contains customer information: CRM exports, spreadsheets, shared drives and departmental trackers. Classify each field as required, useful history or obsolete. This prevents legacy clutter from becoming permanent simply because it is easy to export.
Map to the new operating model
Map contacts, companies, opportunities and relationships into the target model. Standardize picklist values, decide how duplicates are resolved and identify owners. Preserve stable identifiers where they help reconciliation, but do not keep source-system structure that no longer serves the business.
- Source inventory
- Field classification
- Duplicate rules
- Mapping
- Sample import
- Validation
- Cutover
Validate a sample before full cutover
Import a representative sample and test relationships, permissions, reports and edge cases before the full migration. Reconcile record counts and spot-check important accounts. Define the cutover window, source freeze, validation owners and what happens if a critical issue is discovered after launch.
Common questions about this topic.
01Should all historical CRM data be migrated?
No. Migrate history that remains useful for customer understanding, reporting or compliance, and archive obsolete material separately when appropriate.
A good rollout starts with the records and active workflows people rely on now, then brings historical detail across where it improves day-to-day decisions. This keeps the transition understandable for the team and gives you a clean point to validate ownership, fields and workflow rules before expanding further.
02What should be tested in a CRM migration?
Test counts, relationships, ownership, structured values, permissions, reports and representative high-value records.
