Challenge

Upgrade old production code where a clean rewrite is unrealistic and every broad change can break a working business path.

Solution

Reproduce failures, isolate the real layer, apply minimal compatible changes and add logging, performance and security improvements around the legacy core.

Result

A safer upgrade path with a smaller blast radius and code that can be maintained after the emergency is over.
