Know. (dep-solve bug)

... Beyond that, I once (RH8?) suffered from a kernel OOPS during an
upgrade - left me with a dead OS. Since then, I never attempted to do an
upgrade on a live system. (Though I continue to test the upgrade
procedure on VM's for the sake of my co-workers)

Other then that, doing a fresh install + manual migration (configuration
files, etc) is actually faster then the upgrade option. (And gives you a
cleaner OS - especially if you are using 3'rd party repositories.)

P.S. I once lost a Debian installation due to a simple upgrade. (3->4)
This is not a Fedora/RH-only problem.

Doing -anything- on live OS (be that upgrade, or risky maintenance)
without a recent backup is a job-altering-decision.

Lose all your data once (due to a failed upgrade/installation/kernel
crash) and you'll never make this mistake again.

As I said, it's far easier (... and faster!) to do a fresh install on a
spare partition and migrate all the configuration files to the new
installation.

It usually takes me ~90 minutes (including the actual installation over
NFS) to switch from F-N to F-N+1.

Doubt it.
The basic LiveCD is radically different from a fully updated (and well
configured) F8 installation.
