A few days ago, I posted a question which is currently flagged as on hold, due to being off-topic. According to this meta question, a migration will/can/might happen if five users vote to close and at least four of them suggest the same site.
The only information I can find on my question is that five users voted to close, and four suggested Super User.
So my question is how can I determine for myself when this question will be migrated? I don't see any documentation on other requirements to be met. Maybe a moderator on the origin site needs to approve the migration? Perhaps the destination site needs to approve it? Without more information on the question, I really have no idea.
