Not quite. It's impossible to move a question from Stack Overflow to Server Fault or Super User right now, you can only say that it might belong there.
Do you specifically mean "right now" ? As in it has been disabled at the current moment? Because there are plenty of questions that have been moved around from one site to another in the past.
That's great! I thought their issue was that questions are marked off-topic without further handling, requiring users to ask again on a different site.
