How do you test a Microsoft Access migration?
Migration testing must prove both data accuracy and business behavior. Opening the new application without errors is not enough.
Short answer
Migration testing must prove both data accuracy and business behavior. Opening the new application without errors is not enough.
What this means in practice
Testing should be based on real scenarios, known edge cases, permissions, reports, integrations, and reconciled source-to-target data.
✓Compare table counts, keys, relationships, totals, samples, and exception reports.
✓Test each user role and prevent unauthorized actions.
✓Validate normal workflows, corrections, cancellations, and unusual cases.
✓Compare calculations and reports with trusted historical examples.
✓Test integrations, notifications, attachments, imports, and exports.
✓Run a rehearsal of cutover and fallback procedures.
The practical next step
Business users should own acceptance of operational outcomes. Developers can confirm technical behavior, but process owners are the people who know whether the system produces the right result.
This answer provides general guidance. The right recommendation depends on your application, data, users, licensing, and business requirements.
