After Primary Site Region Failure, Service goes into a Degraded state
Perform Manual Failover to the DR Instance
Choose the specific service for which you intend to do manual failover within the My Services App. Then, proceed to the Instances Tab designated for that particular service.
Select the Switchover Option on the top right side.
A pop-up opens up. Select the Manual Switchover Option to DR Instance.
Once the switchover is done, the DR instance becomes the new primary instance. Service is still in Degraded State.
Transition the service to a Ready state by deleting the old primary Instances
Select the three-dot option next to the instance you intend to delete, and choose the "Delete" option from the list.
Confirm your delete choice in the popup
Delete all such instances. Once all instances have been deleted, the service status changes to Ready

Click the "Create Replica" button located at the top right corner of the Instances section, and then select the "Disaster Recovery" option.
Provide the following details as input for the DR Instance:
