Glad to hear it!
Alright Max, we're not forgetting about ya, though we need some more details on your troubles.
Side note: If not already overwritten/if you try again (after another backup first!) could you throw an update log our way?
Failed restore of backup: We're assuming you're on FOSS (you're on fedora afterall) and you backup is just a copy of /opt/zimbra
So if I'm understanding you right, upgrade to .9 failed & you couldn't restore your .7 backup (the one before you tried .7 > .9)
So you restored an even older .6 backup.
What you need to do is get another isolated box up and get the .7 backup working. Pretty much just like you did in

See some of the notes

The goal is to get that backup working on another machine so you can sort through accounts. Even if it's just forwarding lost mail to people in the web-client. Better would be copying stuff back with a thick-client. (If using thunderbird you need to append /tb on the end of the username so the dates don't mess up.) Better still would be if you could handle an imapsync.
