# Migrating question with an accepted answer

The main question that lead to this discussion is: What does $\mathrm{ms}^{-1}$ mean?

Had I seen the question before there were any answers posted, I would have invoked my moderator powers and migrated it directly to Physics, since a physics question is likely to receive a better answer on a physics site. But when I saw the question, it has already been answered, and an answer had been accepted.

So the question on general policy of Off-topic questions that were asked with accepted answers: should we let sleeping dogs lie, or should we close them/boot them to their correct sites?

From this, I gather that the "accepted" status is maintained post-migration; I thus would love to hear about the cons of performing such a migration. (And a user who was not before registered on the target SE site can flag to have his answer re-associated.) – J. M. Aug 29 '11 at 13:14
