Im using zimbra zcs 8.0.0 GA on ubuntu 12.04LTS , is it possible to migrate the settings/mailboxes from old zimbra to "new zimbra server". The new server have ubuntu 14.04.4 x64bit installed with Intel Xeon CPU X3430 @2.40GHz and 15G of ram. I would appreciate any helpful suggestions or links. Thank you
