This was due to SW infrastructure changes within the SZ controller that do not allow this update/restore step to be completed. If attempted, the controller can become unresponsive after the update and subsequent reboot to SZ 5.2 or higher.Symptoms
Immediately after restoring 5.2 backup on a pre-5.2 node and rebooting the new node could experience a fatal error, leaving the node unresponsive and unrecoverable.Resolution
Please refer to the correct process for “Replacing a Controller Node” found in the SmartZone 5.2 Administration Guides for either the SZ100 or SZ300:SmartZone 5.2.0 (GA) Administrator Guide (SZ100/vSZ-E)
