A step-by-step ERP data migration checklist for master data, balances, historical records and cutover assurance. The aim is to help teams identify practical decisions, ownership and controls before changing technology.
Inventory the sources
List every spreadsheet, legacy database and departmental record involved in the migration. Identify owners and data quality problems.
Distinguish operational master data from transactional history and documents.
Set mapping rules
Define destination fields, codes, units, currencies, dates and mandatory relationships. Document how legacy values translate into the new system.
A written mapping specification reduces inconsistent assumptions between teams.
Clean before import
Remove duplicates, resolve missing identifiers and archive obsolete records. Keep a record of decisions about excluded data.
Do not rely on import scripts to repair fundamental business-data disagreements.
Rehearse and reconcile
Run at least one trial migration, then reconcile record counts, key balances and sampled transactions. Test dependent workflows using migrated data.
Assign sign-off responsibility to business owners rather than only technical staff.
Protect the cutover
Set a source-system freeze, final extract process, backup, rollback conditions and post-import verification checklist.
Keep read-only access to legacy evidence for the period required by policy and law.
Practical next steps
- Identify one accountable owner for the process and the records it creates.
- Document the current workflow, including delays and exceptions.
- Agree the control or performance measure that will demonstrate improvement.
- Test the proposed approach with real users before scaling it.
