Is there some information about the subject?
The WIKI is not applicable for the version 6 of Zimbra...
I have to migrate one server this week.
The problem occur for the migration of ldap. It's blocking for the export/import of ldap since the ldap structure have change in the 6.01 version.
Is it possible to copy /opt/zimbra from the 32 bits 6.06 Ubuntu server to the 64 bits 8.04 Ubuntu Server and launch a Zimbra installation migration after? The Zimbra version is the same on both.
