While we upgrade the 5.0 beta 3 to 5.0 rc1, got an error while upgrading the core component.... so the upgrade is failed~ And the ZCS seems cannot be properly start up again..... what we do is rename the original zimbra folder back to the place, however, the zimbra seems cannot be started up in order...
May I know that in case of any failure of upgrade, what's the fall back procedure? As we are using the OSS version, what we can do is setup a daily cron job to backup the whole zimbra folder (stop, tar, start); and then for the restore/fall back part, we just can restore the zimbra folder to the original place (of course, remove the one with error during upgrading)! Does this procedure correct? As we found that the three files (zmsyslogsetup, zmlogrotate, zimbra) are modified like a fresh installed one EVEN we have copied the original zimbra folder to another name BEFORE the upgrade... it's so straight....
