Okay so you are on cpanel, you click the phpmyadmin and it does not load correct. Try mysql and see if that works. You can try to wait a tiny while and it should be back up soon. This is probably just temporary and the servers are probably just recovering from the relocation.
try flushing your dns and clearing your cache.
Try to be patient as well and see if it fully loads. If it comes up with an error, then it probably is just temporary.
Hope this Helped
