It always goes wrong. I've done it like 3 times now. Migrated from one language to another, and then it was taking too long so we rushed it (and also no one was proficient in the new language), so it became an utter mess. So now (3 years later) we're spending another year un-effing it (or trying to). Another one we switched data backends which yielded no performance benefits nor new features and was also rushed. And the 3rd was mostly fine (because it was small) except that it was deprecated like 6 months later because of another mandatory migration. Millions of dollars just wasted writing and rewriting things with little to no benefit.
