Thanks to @the_wifi_guy for pointing out to me that there is an updated version (7/22/01) of the WLC Config Analyzer on Cisco's site.
You'll need a CCO login to download it, and there's also a webex archive explaining how to use the config checker.
If you've never used it before, I recommend downloading it and using it to parse through your current controller configs and see what parts of your config don't meet Cisco's defined best practices.
The config checker is something you need to request access to obtain the proper permissions to download, but that is easy enough to do. The instructions to obtain access are on the WLC Config Analyzer page on Cisco's site.
