My environment consists of a zimbra installation on a Debian 4 box, based on How to install Zimbra Debian 3.1 binaries on Debian Etch 4.0 [Workaround]
Now that 5GA is out, I am considering upgrading. However, given the above hack (I've changed /etc/debian_version back to 4.0 after the installation), I'm not sure how clean the upgrade would be.
Has anyone else tried this yet? Any pointers? Backup, backup, backup goes without saying!
