If you told me five years ago that such a conversion had been done in six weeks, I would not have believed it. Even though some level of source-to-source existed. And I would definitely expect that such a conversion would have resulted in hideous, non-idiomatic code in the target language.
I’ve done something similar to this type of work with an llm. It produces code that is often too idiomatic, in that it introduces conventional approaches that are overkill for the task at hand. But this is almost an ideal scenario, because if the previous tests run clean, the newly converted tests can only fail by being wrong.
They can also silently reduce the tested scenarios, but that’s what code reviews are for.
I use LLM for coding every day. LLMs can totally make something super dumb: oh this test is broken, gatcha, lets replace it with something which is not broken (but very different).

code review of complicated scenarios is about as resource demanding as actually writing code, so shrinking time spent from 1.5y to 6 weeks totally can produce lower quality.
