...I need to kill EVERY single connection I ever made with someone else (just leaving the rooms) and then I get a server at another hosting provider with the same domain.
good old "writing a list of handles that I need to reconnect with" like in the olden days.
And have friends re-invite me to spaces that I have been part of.
I could migrate the entire server, since EMS has full exports, but as said, providers basically say it's not worth the effort and cleanly separating connections is a good enough preparation for a server "migration".
