Currently I'm running 4.5.6 and I would really like to upgrade to the latest version. But in a strange way it seems that I can not find any documentation about upgrading. Is there any documentation?
I'm a bit worried that when I upgrade any custom made settings will be lost. For example, I made some aliases for my domains with zmprov (http://www.zimbra.com/forums/install...e-domains.html), is a setting like that removed?
