We Need to Talk About Migrations with AI

“Using OpenAI Codex, Asana replaced an outdated testing system in two weeks for about $12K.”

The vendor headline is two weeks against a five-year, $6 million estimate. Orosz points out the $6 million was a real number for a job nobody wanted, which is why it never got done. Test migrations are the ideal case here. The output is mechanical, the correctness check is automated, and nothing about the product design is in question. Uber moving 15 million lines is a genuine result. Whether any of this transfers to a migration where the right answer is not already written down is the part the case studies skip.
