Before you can modify a Transport Stream Redundancy, you must first suspend it using the procedure in Suspend/Unsuspend a Transport Stream Redundancy.
Modifying a Transport Stream Redundancy allows you to change the details of the Secondary Input used in the Transport Stream Redundancy.
Once unsuspended, the Transport Stream Redundancy will fail over to the new Secondary Input when the Primary Input is determined to be unhealthy.
The Transport Stream Redundancy must be unsuspended as described in Suspend/Unsuspend a Transport Stream Redundancy to be active.
