"Linux Bible, 2008 Edition: Boot up to Ubuntu, Fedora, KNOPPIX, Debian, openSUSE, and 11 Other Distributions"

This type of installation takes longer than a new install. A new install simply erases all
data on the Linux partitions (or whole hard disk) that you choose.
If you are upgrading an existing Fedora system to this release, you should consider first removing
any unwanted packages from your old Fedora system. The fewer packages to be checked during an
upgrade, the faster the upgrade installation (and the less space used).
You can upgrade to Fedora 8 from previous Fedora systems. The further you are from
the current release, however, the greater the chance of something going wrong. You
cannot upgrade to Fedora from a Red Hat Enterprise Linux system or vice versa.
To upgrade, you must have at least a Linux 2.0 kernel installed. With an upgrade, all of your configuration
files, modified by the installer, are saved as filename.rpmsave (for example, the hosts
file is saved as hosts.rpmsave). The locations of those files, as well as other upgrade information,
are written to /tmp/upgrade.log. The upgrade installs the new kernel, any changed software
packages, and any packages that the installed packages depend on being there. Your data files and
configuration information should remain intact. By clicking the Customize box, you can choose
which packages to upgrade.
