A CRM migration succeeds or fails less on moving the data itself than on whether sales and the back office keep running after the switch. Moving from Salesforce to HubSpot, or to another CRM, the question isn't only deals, opportunities, and activity history — it's how you preserve the connection to downstream work like billing, inventory, and contracts. This guide lays out how to run a CRM migration safely.
Where migrations trip up
| Symptom | Cause |
|---|---|
| Duplicates and inconsistencies explode after migration | No data cleansing before the move |
| Past activity history can't be traced | The scope of history/attachment migration wasn't decided |
| Billing and contracts don't tie to customers | No mapping designed to the back office beyond the CRM |
| Sales don't use the new CRM | Fields and rules were ported as-is from the old CRM |
Step 1: Decide scope and master
Decide what to move (accounts, opportunities, activities, attachments, custom fields) and which becomes the master after migration. Choosing what you use rather than moving everything keeps post-migration operations light.
Step 2: Cleanse before migrating
Fix duplicates, inconsistencies, and gaps before the move. Migrating dirty data reproduces the same problems in the new CRM. Decide merge rules and required fields before migrating.
Step 3: Design the back-office mapping
Design which records in the new CRM billing, payments, inventory, and contracts tie to. Deferring this tends to leave you, post-migration, unable to connect customers to billing.
Step 4: Parallel run and validation
Don't cut over all at once — reconcile against validation data for a period. Confirm counts, amounts, and key fields match the old CRM before moving to production.
How Sanka fits
Sanka supports data cleansing (deduplication) before and after a CRM migration, and the mapping to the back office — billing, inventory, contracts. Keeping the new CRM as the source of truth for sales while tying it to downstream records, you preserve a consistent path from customer to billing and contracts after migration.

Summary
A CRM migration succeeds less on the technique of moving data than on narrowing scope, cleansing before the move, designing the back-office mapping, and validating with a parallel run. Beyond moving data, designing so that customer-to-downstream stays connected after migration is the fastest route to adoption.
