Folks; I'm again looking into finally upgrading our Ubuntu 10.04 based e-mail server. Tried this several times in the past and (repeatedly) failed; that's why I gave up on it yet in the end we need to get away from 10.04 at some point.
Here's my setup: The VM includes cyrus imapd, postfix, a local mysql database hosting virtual aliases all along with postfix-mysql and local user accounts. Obviously, this system is critical for our business, transports > 5k messages per day and has a spool of roughly 500g of mail in shared IMAP boxes, as well as a modestly complex set of cyrus ACLs controlling access to the IMAP boxes. Completely setting this beast up all anew is tough and risky and as it generally works, I just wanted to do a step-by-step dist-upgrade of the base system to the most recent version. Unfortunately, this doesn't really work well due to a couple of changes especially in cyrus-imapd. Has anyone successfully dist-upgraded such a setup and can share some hints, tips, ideas with me on how to get it done well? TIA and all the best, Kristian -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
