Best practice: back up data. fresh install f8 from dvd or hard disk method.
Next best: dvd upgrade.
Last: yum upgrade.
Still wise to back up your config and data before upgrade.

In both cases, peruse the following to get insight into changes and 
issues between versions:

especially:
- libata introduction causing /dev/hda's -> change to /dev/sda's
- needing labeled partitions
- disk driver obeying HPA areas.
- check for volume errors
- check for selinux labelling gone wrong

There is also some projects working on improving yum upgrade process / 
info, and another for preparing systems for upgrades. Any weird things 
you find might be of use to either of those projects.
