Replace a Unit in Firewall Threat Defense High Availability Pair

To replace a failed unit in the Firewall Threat Defense high availability pair using a backup file, see Restoring Cloud-Delivered Firewall Management Centers and Managed Devices in the Cisco Secure Firewall Management Center Administration Guide.

If you do not have a backup of the failed device, you must break high availability. Then, register the replacement device to the Cloud-Delivered Firewall Management Center and reestablish high availability. The process varies depending on whether the device is primary or secondary:

• Replace a Primary Firewall Threat Defense HA Unit with no Backup

• Replace a Secondary Firewall Threat Defense HA Unit with no Backup
