Can I change distros

Hey

Just wondering if I can back up my open source zimbra on centos and restore it to a fresh copy of ubuntu.

Phoenix's directions with changes for your situation:
This is with no modifications to IP or FQDN -ie: using the same ip and server name as before
-Backup the /opt/zimbra directory on your current server (and any other data locations if you have them symlinked or mounted elsewhere
-make a note of the gid & uid of th zimbra (and postfix user)
-Do your os switch
-Install the SAME release on the new Zimbra server as you had on the old server (ie if your currently running 4.5.5 on centos use 4.5.5 for ubuntu)
-Make sure it's all working then shutdown zimbra and copy the files from your storage location/backup (or old server to the new one if you we're switching boxes as well)
-Make sure the uid & gid is changed to the ones you had on the old server
-Run zmfixperms
-Make sure the LDAP password is set (check the wiki or forum for details).
-Do an upgrade install on the new server and you should be good to go.
