I don't think anyone is advocating writing tests for one-time data conversion scripts. Certainly I am not.

I think you've confused all the things that you think I said into newer meta-things that I haven't said.
Rule 6, "Testing will go on as long as it has to." only matters if you're optimizing. If you're not optimizing (or any sort of refactoring) that data conversion script, then no testing need take place.
