we are using 2 Wireless controllers in a Cluster (v2110) & along with 180+ wireless AP 3825i and we are planning to upgrade the controllers into v9.21.19.
(Current version : 9.21.07 )
Our plan of action is like :
- to separate the controllers from the Cluster and going to upgrade only one Controller into 9.21.19.
( Note : Each controller registered with 80 Wireless AP 3825i. )
So, we need to remove the controller from the Cluster.
Thank you ,
