I liked the question, and was rather surprised to see the comments saying that it's ambiguous.

I suppose that people have got so used to MS thinking they have done something useful when all they've actually done is create a shoddy mess that they have come to believe that "migrate a script" means "bodge up something that has no chance of working"; the question is only ambiguous if that is your meaning for "migrate" - of course it is MS's meaning, but MS sometimes get things wrong, don't they.
