excellent, thanks. Im actually in the process of eliminating the 4400's. I just need to join the 5500 to the mobility group and start moving the AP's over. I guess once I do that I will upgrade the code on the 5500's. Thanks!
I was looking at copying over the config from the old controllers to the new but it looks like the configs are not like standard configs (like switches and routers). Is that the best way or is there a better way to prep the new controllers to add them into the mobility group? Right now I am going page by page in the gui and making the changes.
