For people who can a complete re-install is probably best. One reason for that is the inclusion of ext4 in Fedora11. You won't get the benefit of ext4 unless you do a fresh install or upgrade from ext3 to ext4. If you read the upgrade guide that Fedora produces it recommends not doing an upgrade.
This time around I decided to go with PreUpdate right off the bat and it worked great. Here are the condensed steps. I think this will be the last time I do an upgrade post since they have it down to almost nothing now.
- You have to be at Fedora10 before you try this. If you aren't there follow the steps to get to Fedora10.
- yum clean all
- yum udpate
- preupgrade-cli "Fedora 11 (Leonidas)"
- reboot and wait
It seems like the days of conflicts before upgrades are gone now so that is a good thing. I didn't have to remove anything to make dependencies work out. The only fallout I had from this upgrade was my NVIDIA configuration for xorg got wiped and I had to pull it from backup. So take note to back up your xorg.conf if you have a custom one.
