Restoring old version

[hodel]

I had problems with the upgrade from 3.0.0_M2 to 3.1. When restored my backup copy to /opt/zimbra it wouldn't start. Is it possible to do a clean install of 3.0.0_M2 and restore datafiles to get mail working again?

What were the errors on statup? Did you run zmfixperms.sh(as root)?

The problem I was having was that it was asking for a password when it was starting LDAP.

I did manage to get the old version working again by installing 3.0.0_M2 and then restoring the backup files.
