When doing your upgrade to wordpress 2.3 , I suggest you test it out by first using a local copy on your computer.

NEVER DO AN UPGRADE ON YOUR SITE WITHOUT TESTING IT OUT LOCALLY FIRST. When you do it locally, you can still recover your local blog when something wrong happens.

Disclaimer: This guide will try to help you in your attempt to upgrade your existing blog to Wordpress 2.3. I do not claim that this guide will work for you 100% flawlessly but this is just how I did it. It is up to you if you want to continue reading however, please do not blame me when something goes wrong. ^_^
