I'm running Zimbra 7.1.4_GA_2555 + patch-7.1.4_GA_2568 on Ubuntu 8.04 32-bit. Now I have to move the Zimbra installation to a new server because we are migrating from XenServer to VMware.

I've been following the Wiki to the letter. The problem is when running the installation over the rsync:ed /opt/zimbra on the new server. I get a lot of LDAP related issues like "LDAP failed with exit code 256".

Can it be because I run a GA_2555 installation over a GA_2568 patched /opt/zimbra?

The migration seems to works if I run a 7.2.1_GA installation over the rsync:ed /opt/zimbra. Is that a recommended way to solve my problem?
