We just completed upgrades of our 4400's last week. We went from 188.8.131.52 code to 184.108.40.206 to 220.127.116.11. The WCS code upgrade was the tricky part, we had wanted to go to the 5.2 train from the 18.104.22.168 code version. Both our vendor and Cisco TAC recommended we perform a backup - uninstall - restore upgrade for the WCS. It actually wasn't bad at all, do read the release notes and when in doubt call Cisco and have them sanity check the upgrade path you plan to take. Good Luck.
