We're pretty far behind in Zimbra updates. We're currently running 6.0.5_GA_2213.DEBIAN4.0.FOSS and want to upgrade to the latest version. We have a new "fearless leader" and he wants to move to Google Apps...but before we make any decisions I want to level the playing field by upgrading to the latest version of Zimbra. It's a long story...
Since we're so far behind, our server is running Debian 4 (Etch). Ultimately, I'd like to move to Ubuntu LTS 10.04 64-bit, but we need to update before I have time to do that.
What is the best way for me to ensure that I update the server to Debian 5 (Lenny)? Our current sources.list file is the following:
Can I simply change "etch" to "lenny" and then do an apt-get upgrade, or will I need to do an apt-get dist-upgrade? I want to ensure that I upgrade to Lenny and NOT Squeeze (6).
deb http://sluglug.ucsc.edu/debian/ etch main
deb-src http://sluglug.ucsc.edu/debian/ etch main
deb http://security.debian.org/ etch/updates main
deb-src http://security.debian.org/ etch/updates main
How will this affect my current Zimbra install, and will this massive change affect my upgrade success?
Any help is much appreciated!
