Re: Bugs with mixed Zimbra 7/Zimbra 8 cluster



> 1) When I performed my upgrade I just created new boxes that ran zimbra 7 migrated all the users to the new boxes and then upgraded the new machines to 8.0.4.

The proposal is to go from RHEL5 to Ubuntu 12. RHEL5 cannot run ZCS8 and Ubuntu 12 cannot run ZCS7. So I'm looking at account-by-account zmmailboxmove and prolonged coexistence.
