...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".
Hold up. If they provide full backups and you fully control the domain, at which point does it break the keys? Don't they include secrets in the backup?
I've migrated my server, like, three times, and never experienced key issues.
