MiCollab borked after attempting domain name change

[augiedawg6123]

Attempted to change domain on MiCollab server, and it borked it completely. Put the domain name back, and it permanently messed up my users. This is a known issue:

Mitel MiAccess Login

Mitel is telling me without a backup I have to spin up a new MiCollab server!? Surely someone has a way to fix whatever the heck the domain name change broke. Spinning up a new system here and hadn't taken any backups yet...
