I have a Multi Node Installation: 2 MTA and 1 "Full Zimbra" Node (mailbox, ldap, etc).
I want to upgrade the "Full Zimbra" node to a HA Cluster, on RH Cluster Suite, but im not sure about the procedure.
What im thinking is to take a full backup, then delete all and do a Cluster installation following the docs. When the cluster is working i'll do a recovery following the Disaster Recovery guide.
will this work?
