How will moving to another server rectify their problems? Each server is artificially limited on the number of logins for gameplay at present (aka "we are monitoring the bandwidth") - SE has only commented on the non-availability of character creation services. They're an established community, so unless the server can support a full character load concurrently, there's no guarantee that even if all the characters were moved to another server they would be able to login concurrently. Almost certainly if the dozens of members moved to another server, they would be hit with some number of 1017.

There's little choice but to wait.
