From the technical overview:

To upgrade from Ubuntu 11.04 on a desktop system, press Alt+F2 and type in update-manager (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '11.10' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 11.04 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.

Upgrading by using the CD or USB image

From 11.04 onwards,when you boot the livecd and start installing it will give a option of upgrading to 11.04. it will automatically detect installed apps and install the updated version of your apps also. Assuming you're not dual booting.

Upgrading using the command line:

• Run do-release-upgrade in a terminal
