Hello, I have been tasked with the job of upgrading our Zimbra Open Source edition with not only just Zimbra but as well as the server. Here are some details on the current and new set up:

Current setup:
OS: Ubuntu 10.04 LTS 64bit
Zimbra: 7.1.2_GA_3268.UBUNTU10_64 UBUNTU10_64 FOSS edition

New setup:
OS: Ubuntu 12.04 LTS 64bit
Zimbra: Release 8.0.3.GA.5664.UBUNTU12.64 UBUNTU12_64 FOSS edition

These are on two different servers and my question is, can I just do an rsync /opt/zimbra and setup LDAP on the new server and it work they way it should, or is there more to migrating all the content over from the old server to the new one?
