I remember a similar story shared this year at JAX2026 from the Sparkasse Group, they said they were using AI to migrate from COBOL, but they still were in the middle of the migration. Maybe they faced the same issues / problems? It seemed pretty zealous to me, that everything was working smoothly, but this article highlights the limitations

Yeah nah maybe fix the bugs before swapping the average COBOL dev for the average Java dev.

sometimes if the bug exists for enough time it is intended behavior
surfingdino•10m ago
Indeed, there may even be a whole lot of code that depends on it.
wwind123•1m ago
Yeah. Bug-for-bug migration is a real thing in large code-bases in the industry. You want to replicate all behavior of the code regardless whether the behavior is a feature or a bug.
