I used the mgaapplet-upgrade-helped to upgrade, which, from my understanding, is fairly close to just using urpmi and here are a couple more notes:
fglrx: 0) I have a dual monitor setup with a smaller monitor to the right of a large monitor. 1) I'm not sure if I was using an install of the binary driver from AMD's site or the fglrx package, but it booted straight to a frozen system 2) None of the kernel-mode options would let me boot into a graphical interface 3) xdriver=radeon let me get to a non-responsive system, which would respond to ssh 4) After using another system to ssh in, enable non-free and install radeon-firmware. X still failed to start, but it seemed to be because of a bad Xorg.conf setting: bad screens 5) I tried different XFdrake options, but they all told me that I didn't have any valid screens and that I should try to change the settings. 6) Using the proprietary driver allowed X to start. 7) I had to use the Catalyst control center to setup my monitors properly. firefox: 1) The language in Firefox was set to English / Hong Kong and not United States for some reason. I'm pretty sure it was set to United States in Mageia 1. KDE panel: 1) Some of the logins for my computer have screwed up panels: both task mangers, no task managers and one had only the Application Launcher Menu 2) I have the new MCC icon in the panel, but the menus have the old icon --Jeff
