After migrating data, which step helps ensure data integrity?

• A. Run a balance sheet report only.
• B. Reconcile statements for bank accounts only.
• C. Review and reconcile post-migration, including checking lists and accounts for accuracy.
• D. Delete migrated data and re-migrate.

Answer: (C)

After migrating data, you verify that everything moved correctly by doing a post-migration review and reconciliation. This means systematically checking that key lists—such as customers, vendors, items, and accounts—are complete and match the source data, and that balances and totals in the new system align with what they should be. Reconcile major accounts to confirm opening balances and transaction totals are accurate, and look for duplicates or missing records. This comprehensive check ensures data integrity by validating that the migrated data is complete, correctly mapped, and consistent across the system.

Running a balance sheet alone doesn’t prove data integrity because it only shows a snapshot of finances and doesn’t verify that every record migrated properly. Reconciliating bank statements focuses narrowly on cash accounts and bank activity, not the entire data set. Deleting migrated data and re-migrating is destructive and not a validation step. So, a thorough post-migration review and reconciliation of lists and accounts for accuracy is the most effective approach to ensure data integrity.
