This is how I got my Raring install in the first place back in November. and being unable to get a Raring ISO image to work I converted a second Quantal just the other day. A lot of updates need to be done but it will still work.

sudo sed -i 's/quantal/raring/g' /etc/apt/sources.list
That changes the repositories. Follow it with the usual

sudo apt-get update
sudo apt-get upgrade
I am planning later today to install Gnome Remix. That will be Quantal and then use this method to convert it to Raring. If it does not work in this case I can easily re-install the 12.10 Remix.

This is pretty awesome!!! Used it to go from quantal to raring.

Thanks for sharing.
