>...., so for example in case of any complete shutdown or lack of consumed power in site A, the AP’s will directly..
Ok , but will the APs then remain alive too ? Will it be reasonable to keep a wireless service running for customers ?
Anyway you can look at N+1 redundancy between HA-SSO pairs on different sites , for instance.

I'm afraid my idea wasn't clear enough, i will try to explain with a an illustrative image
so, let's imagen that in Site the controller management IP is 192.168.1.50/24 with its having its own standby controller if its fails.
the other site controller management IP is 1.1.1.50/24 with its having its own standby controller if its fails.
I want if site A both primary and secondary controller fails it migrates all its AP's and wlan to the controller in site B until it the primary controller in site A reconnects back, and vise versa.

Hello @mm-501
One possible scenario for you would be the AP from site A to have the WLC cluster management IP address from site B as a secondary WLC in the AP availability tab. The same you can do on the site B using the management IP address from site A.
This way, if one side goes down, the AP will migrate to the other side and this is called HA N + 1.
Keep in mind, however, during the AP migration there will be clients disconnection as the AP will reload.
For WLC 9800 look at "Configuration on Access Points"

Meaning, is it impossible to have N+1 and SSO at the same time ??

Actually the idea I provided uses both at the same time. The HA SSO will be used between WLC on the same site, this is what you have today.
The N + 1 is done by pointing the high availability tab on the AP to the other site on the Secondary WLC option
