I just finished the upgrade on this server from Ubuntu 7.10 ‘Gutsy’ to Ubuntu 8.40 ‘Hardy’ and all I have to say is Ubuntu 8.04 Rocks My Socks! Here is a bit how things played out…
I spent a bit of time backing things up and preparing for the upgrade (you know, just in case). I then switched my repository to a faster mirror than the local one I had been using and I installed the required package to handle upgrades (update-manager-core). After this I ran
sudo screen do-release-upgrade and watched the fun happen. (Yeah, I ran it in screen because I didn’t know how long it might take and I wanted to be able to detach if needed..)
Guess how long it took? Less than nine minutes! In less time than it normally takes to even download the CD I was upgraded, rebooted and back in production! So far things are running great, the upgrade went as smooth as can be, and my world has been rocked by Ubuntu Server!
I just have to say, if you or your company has been wondering whether Ubuntu is ready for the server, all I have to say is HELL YEAH IT IS! Try to upgrade a production machine from one release to the next and have it back in production in less than 10 minutes another “Enterprise” Linux distribution. Ohh, and do it while its still in production without any CDs.. I dare ya!
