How to configure HA with cisco virtual controller (vWLC)

[AlexandreOppermann]

I need to know how we can configure HA between two virtual controllers. What are the physical connections? And settings needed to work?

I didn't understand about the mobility group, how should I configure between the new and the old controllers? because in the old one there is no mobility group configured.
and if I configure below, it will no longer work?
configure them in the HA tab of each AP as two additional WLC. If you put them in place 1 and 2,

Correct me if I'm wrong, I'll create a new test SSID on the new vWLC controller, they don't need to roam for now, should I still configure a mobility group between the old and the new controllers, or only the new ones?
