For Akaunting, move a small but representative accounting period into a test environment. Include unpaid invoices, partial payments, expenses, taxes, and at least one correction. Compare customer balances, bank totals, and period reports with approved figures from the original system.
Inspect attachment links and account permissions as well as numbers. Confirm which data can be exported later and how backups are restored. The migration should have a cutover date, a read-only archive, and sign-off by the person responsible for the books. Do not infer financial accuracy from the fact that records appear in a list.
