Via “Switch class…” in the Network block. First a plan per host shows whether Clusterward moves or creates the record or whether you change it yourself, and what happens to the certificate. Then Clusterward rolls out the service with both controllers, each with its own class, moves the records in registered zones and completes the switch one hour after all hosts point to the new address. Until then it can be aborted; if a host already points to the new address, the way back runs as a cutover again.
