What is data migration?
Data migration is moving data from one system to another, for example from spreadsheets or an old CRM into a new ERP, while keeping it complete and usable. A well-planned data migration covers mapping, cleaning, test runs and the final cutover.
Why it matters
A new system is only as useful as the data you bring into it. Duplicates, missing fields and broken links between records surface on the first day staff use it. Plan the migration as its own project, with test runs and a sign-off, rather than an afternoon task before go-live.
1MappingEvery field in the old system is matched to a field in the new one, with rules for the gaps.
2Test runsTrial migrations into a copy of the new system let users check real records before the cutover.
3Personal dataCustomer and staff records remain personal data during the move, so limit who handles the export files.
ExampleA distributor in Almaty moves from an old accounting program and several spreadsheets to Odoo. The team maps customers, products and open invoices, merges duplicate accounts and runs trial migrations that sales and finance check. The final move happens over a weekend, and the old system stays read-only for reference.
