Apart from recommending the user to backup the files that matter to them.
Another thing that is important and should be recommended is for the user to try/test the new ubuntu version first.
And this can only be done right now with a disc or usb stick.
So if you insert a disc/usb one can be automatically created for you.
Once the user has tested the new version and verified everything works and the performance is still acceptable on their hardware, then they can choose to install/upgrade, right there from the disc/stick.
I think testing it first avoids some headaches and wasted-time by having to revert everything back to a previous state/version later on.
Sure, You can still upgrade without doing the recommended steps of "testing and backing up", but do so at your risk, only if you know what you're doing and have experienced to fix potential problems yourself.
