3. Specify if you want to perform an immediate or graceful failover. An immediate
failover begins immediately without waiting for the data queues on the source and
target to empty. A graceful failover waits until the queues are emptied before
continuing. If you select the graceful failover, specify how often you want the
failover prompt to continue asking for failover while there is still data in the queues.

environment, you should use the graceful failover option so that
the source cluster resources are taken offline gracefully.
File Server Note: The graceful failover option is not available.
