Upgrading Fedora 11 to 12 using yum
As with the Fedora 10 to 11 upgrade, you can upgrade Fedora 11 to Fedora 12 using yum. I find this to be the easiest and most reliable way to upgrade a Fedora installation whether you use it as a server or desktop.
To reduce the total data downloaded, I’d recommend installing the yum-presto package first. It downloads delta RPM’s and builds them on the fly, which allows you to upgrade packages without having to download the entire RPM’s.
Ugly upgrade path from WordPress 2.7.1 to 2.8

I was perplexed at the error, so I restored from a backup and began upgrading manually. The manual upgrades have always worked well for me in the past, so I figured this would probably fix the problem.
