Adding a second controller

[mruhenkamp]

I have one 50 license wlan controller and have maxed out it licenses. I want to add a second controller and convert the remaining APs I have to lightweight. How do I setup the second controller will all the same SSIDS, WLANs, etc? Is there an automated way? I want clients to be able to roam across access points on the 2 different controllers without issues.

The 2nd controller will need to be setup with the same SSID's VLANS and so on. After your interfaces and ssid's are created you will need to setup a mobility group with both controllers for fast roaming.
