How can I upgrade my Ubuntu Server to Karmic?

I have an Ubuntu Virtualization Server which I have been using for a quite some time. Now that Ubuntu 9.10 released I would like to upgrade it to the Ubuntu 9.10 Karmic release.
First you need to install the update-manager-core package.

kok@fhome:~$ sudo apt-get install update-manager-core

After installing the update-manager-core package, complete upgrade procedure is just executing following command.

kok@fhome:~$ sudo do-release-upgrade

After executing the command above, Ubuntu did a check on my system and inventoried all the packages needs to be installed and removed.For my virtualization host complete upgrade process took less than 15 minutes.
