We have a cluster with up to 250 APs. The cluster comprises of 2 SZ-100. The controller that has the licenses associated with it and wich was the one were the cluster was originally created died. In order to replace it, what is the procedure? The documentation is somewhat vague. Do I only need to setup the replacement unit as a new cluster, with the same network setting, cluster names and hostnames? I'm asking this because I think that, since the second (operational) unit says that not all planes are in service, attempting to make the replacement unit join the cluster will result in failure. Am I correct?
What is the best procedure for replacing the unit?
