After completion of the database/application failover testing, we need to get the DR site back to normal mode, i.e. the state where the pod is in the demoted state and continuously applying the replication stream from PROD.
Demoting the DR pod will cause any test data written into that pod to be discarded from the pod. When a pod is demoted, Purity creates an undo pod. This undo pod is a special object that, if cloned, can be accessed as a new pod to gain access to that data.
For demoting the DR pod, we need to do the following:
1. Stop the database
2. Unmount the filesystems or ASM disk groups
3. Demote the oraprd12-pod-dr pod
