When the PlateSpin cutover operation is complete and the virtual one-node cluster comes online, you see a multi-node cluster with one active node (all other nodes are unavailable).
To perform a PlateSpin cutover (or to test the PlateSpin cutover on) a Windows cluster, the cluster must be able to connect to a domain controller. To leverage the test failover functionality, you need to migrate the domain controller along with the cluster. During the test, bring up the domain controller, followed by the Windows cluster workload (on an isolated network).
