Backup data and install with the standard installation CD. Personally I have two hard drives, one with the system stuff and the other with personal data. Makes updating very easy, you could do the same with partitions on a single drive.
Upgrading from previous versions is best only done when you have not tinkered with your install between release. If your like me and over time pulled everything out and put it back in the wrong place etc then fresh installs are the way to go.
