Performing Primary/Standby Switchovers in Batches

Function

This API is used to perform primary/standby switchovers in batches.

Constraints

This API only applies to tasks in the Disaster recovery in progress or Disaster recovery failed status. A switchover can be performed when the DR database can be properly connected. Dual-active DR does not support the switchover.
