Zimbra HA setup

[Rama]

Hi All,

My Zimbra is running on a single VM with all required components. As of now Zimbra version is 8.0.3_GA_5664. Since, users accounts are grown and time has come to upgrade Zimbra that should run in a cluster. Can anyone please suggest best cluster setup that will work active/active with HA, sync mailboxes and replicate data over mailbox servers.

Thanks in advance.

The first thing to mention is that you should be on the most recent release of ZCS, now! The second is that you should look at some of the wiki articles and forum threads on this topic and if you have any questions then ask again. BTW, you've posted this in the wrong forum, I'll move it.
