So I have heard a lot about migration but actually finding any kind of schedule is impossible. Any clue people?
From what I heard, the terms of server migration can be seen in the game settings menu, further explanation instructions can ask the forum admin
The migration people are talking about is the ability for R5 to recruit from other servers for the event. Think of it as a test run of the alliance before commiting
Here would be a good resource for you:
I have a made post that is related to your question and should answer your question.
