Every long-running business has one: an Access database, a decade of spreadsheets, or a custom system whose author left in 2015. It still works, which is exactly why replacing it keeps getting postponed.
The hard part is never the new system, it is the history. We extract, clean and reconcile the old data first, and prove it balances before anything is switched over. Records that cannot be reconciled get reported rather than quietly dropped.
We run old and new in parallel where the risk warrants it, so there is always a way back.
What is included
- Audit of existing data, including quality problems
- Extraction and cleaning scripts
- Reconciliation report proving nothing was lost
- Parallel run before cutover
- Rollback plan
- Archive of the original data in a readable format
