Removing an Identity Server from a configuration disassociates it from the cluster. The configuration, however, remains intact and it can be reassigned or assigned to another server.
On the Home page, click Identity Servers.
Click Server actions > Stop the Server. Wait for Health to turn red.
Click Cluster actions > Remove from the Cluster.
For information about deleting an Identity Server, see Managing a Cluster of Identity Servers.
IMPORTANT:When a cluster contains only two Identity Servers, introduce a new Identity Server to the cluster before removing the other Identity Server.
