I'm facing a difficult dilemma here: several months ago, I asked a question on Stack Overflow that should have been posted on Superuser instead, and the question is now too old to migrate. In this case, would it be acceptable to post a duplicate of the question on Superuser.com, since there's apparently no other way to migrate it now?
I'm concerned that the question would be downvoted for lack of research effort if I posted it on Superuser, since it already has an answer on Stack Overflow. On the other hand, if I didn't migrate the question, then it would eventually be deleted, and then I wouldn't be able to migrate it to the correct site. I would post a duplicate of the question on Superuser and then delete the original Stack Overflow question (if that were possible), but there's no way to delete the question now, since it already has an answer.
