Disallow voting on answers if question is migrated

  1. I have asked a question https://stackoverflow.com/questions/14171460/what-is-session-leader-in-ps-ax?noredirect=1 on Stackoverflow.
  2. I up-voted the good answer and accepted it.
  3. Later the question is moved to Super user as What is session leader in `ps ax` along with its up-votes and accept tick-mark.
  4. Now can I up-vote the same answer again?

Why is that? Didn't I just vote on it? Shouldn't it be prevented?
