I have a few servers (virtual and physical) and all of them run Ubuntu 6.06 LTS (aka Dapper Drake). Until now. I did my first [LTS to LTS upgrade](https://help.ubuntu.com/community/HardyUpgrades#head-e7f287c730b93116f89de7ea7e05efbe95fa6dd1) and it went without a hitch. So now I’m running mostly 6.06 servers and one 8.04 server.
I was very brave, maybe foolish even. I didn’t create a snapshot of the server before I started. 😎 I just did the upgrade. Apache upgraded fine as did MySQL, Django, Python and Samba. There are some warnings about upgrading SSH in place but I did it and had no issues. There were numerous warnings about needing to upgrade grub that scrolled by but the installer handles these for you automatically so you can disregard the warnings.
I did this because I wanted to install [couch db](http://incubator.apache.org/couchdb) ([via](http://eric.themoritzfamily.com/2008/04/08/your-own-appengine/)) which is an exciting distributed database project. My first impression is that it is an excellent and exciting project but I will do more investigation and report later. In the meantime, test the LTS to LTS upgrade!
