If you want to do it quickly then build a new server running Hardy, give it the same hostname and ip as the old one, install the same version of Zimbra to it so you know the pre-reqs are met and then copy /opt/zimbra from the broken server onto the new one. (make sure zimbra is stopped at both sides of course)
That should get you up and running, it's unlikely that the upgrade would touch any part of zimbra, it's more likely just changes enough to upset it, if you have the time to look for the cause of the problem that that would be better, but I see no reason why a 'box swap' would not make the problem go away.
