 Upgrade 3.0 GA to Latest release
I was recently hired by a new company and noticed that they are running a very old version of Zimbra 3.0 GA. I was wondering if I could do a upgrade straight from 3.0 to 4.5.1 (or latest) or if i would need to do a incremental upgrade (i.e. 3.0 -> 3.1 -> 4.0 .....) |
