It started as a scheduled job. Then a queue was added, then a retry script, then a spreadsheet that somebody checks on Tuesdays. The logic that decides whether a customer gets billed correctly now lives across four systems and one person’s memory, and that person is retiring.
Everyone agrees it should be replaced. Nobody will approve a rewrite, because the risk of getting it wrong is measured in customers and regulators. The way through is not a bigger project. It is a smaller first step that proves the new path is safe before the old one is switched off.
We map what the process actually does, which is rarely what the documentation says. Code, jobs, integrations, manual steps, and the exceptions people handle by hand.
Execution path and dependency mapping
Manual step and exception discovery
Business rule extraction and validation
We design the replacement around the failure conditions the process will meet. Long-running state, partial failures, external systems that time out, and changes that arrive mid-flight.
Durable execution design
Idempotency and exactly-once handling
Versioning and safe change design
Traffic moves in slices. Both paths run in parallel and are compared on live data until the new one is trusted, which is what makes the cutover uneventful.
Slice-by-slice traffic migration
Parallel run and output comparison
Rollback design and rehearsal
The old path comes down only after the new one has been proven under real conditions, and your team leaves knowing how to operate what they now own.
