First release to include bits to make upgrades smoother... with Obsoletes: in blag-release & new ks-upgrade.cfg
evolution-data-server to 1.6.1-1.fc5.2 from 1.6.2-1.fc5.1
In sum, you can test doing 30k to 49k upgrades with this CD image and you should have reasonable luck. ;)
After the upgrade try running:
apt-get -f install
To see if it'll clean up any other repo bits you may have added.
