Last week I started our migration from VMWare’s VI3 to vSphere. There are many improvements to the load balancing capabilities as well as the management capabilities. The storage engine has been greatly improved as well. Storage vMotion is available in the GUI without a plugin and thin provisioning is finally available, which is a huge boon and reason enough to make the move on its own. Most of this process can be completed with no downtime for the virtual machines.

So, now that Hardy Heron is out, I’ve gone ahead and upgraded my server. It took a little while, but overall it went quite smoothly. Having the ability to go back and forth between the old server image and the new server image made it a much easier experience. Big thanks to Linode and virtualization.
Changes
One large change I made to my configuration is using Dovecot’s sasl authentication for Postfix rather than Cyrus. Dovecot really seems to be making headway in the mail server market. I strongly reccomend it to anyone looking for a decent IMAP server.
I’ve also upgraded to WordPress 2.5 and a later version of Roundcube for webmail. Unfortunately, Ubuntu seems to be holding Roundcube back a bit in their package repository. I’m not sure what the holdup is, but they’re at least one version behind at the time I’m writing this. For that matter, WordPress is a couple of releases behind as well. I guess that happens with an LTS release.
Todo
I’m still having a bit of trouble getting WordPress’ permalinks working correctly, so you’ll probably notice that some of the links aren’t working properly on the blog. I remember having this problem in the past, but, for the life of me, I can’t remember what I did to solve it.
Update: Got the permalink issue taken care of. Apache must be told, with the “AllowOverride” parameter, to allow .htaccess files. If this isn’t done, they will be ignored.
