When teams modernise a product, the conversation is all about the new platform: a new language, a new architecture, a cleaner interface. One thing rarely makes it into the strategic discussion, yet it often carries the greatest risk of the entire programme. 🎯
It is the testing network. Years of accumulated tests that quietly hold together traceability, validated behaviour and the confidence that every release still works. The moment the technology stack changes, that safety net becomes exposed, and rebuilding it from scratch can cost more than rebuilding the application itself. A few things worth your attention:
● The counterintuitive decision that cut test migration effort by roughly half, and it was not about writing tests faster
● How a system of over 1,500 automated scenarios and 900 requirements moved from desktop to web without resetting product confidence
● Why the smartest move in one migration was to translate meaning rather than code, using natural language as the bridge between two stacks
● The exact role AI played, and the one thing it was never allowed to decide 🤖
The real question in any migration is not whether the system can be rebuilt. It is what should never be rebuilt at all. 🤔
