Upgrade 4.5.6 to 4.5.9

[bramm]

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 (Multiple domains?), is a setting like that removed?

Unless you've made any changes to Zimbra config files manually then your changes via zmprov will persist. There is no documentation for the upgrade because all you need to do is './install.sh'.
