Does DRS Support Backward Migration/Synchronization?
DRS real-time migration and real-time synchronization tasks cannot be reversed.
A single-active DR task can be reversed through a primary/standby switchover.
Different from single-active DR, dual-active DR involves forward and backward DR tasks, and primary/standby switchover is not required.
