Promote a Replica Instance for Disaster RecoveryPromote a Replica Instance for Disaster Recovery
This procedure removes a malfunctioning primary instance from the deployment and promotes a replica instance to be the new primary instance. Promoting a replica instance restores the ability to administer a deployment.
While the replica instance is being promoted, users cannot authenticate to the replica, and you cannot perform any administrative functions, such as adding users.
If the original primary instance and all replica instances are online and functional, then you can perform a promotion for maintenance. For more information, see Promotion for Maintenance.
Before you begin
You must be an Operations Console administrator.
