Break Out-of-Band High Availability
If you break an FDM-managed HA pair using the FDM interface, the configuration status of the HA pair in Security Cloud Control changes to Conflict Detected. After you break HA, you must deploy the changes to the primary device through FDM-managed and then resolve the Conflict Detected state in Security Cloud Control.
After the device is back in the Synced state, you can deploy configuration changes made in Security Cloud Control to the device.
We do not recommend reverting changes from Security Cloud Control after breaking HA using the FDM-managed interface.
