Unregistering NSM

You can unregister your NSM On-Premises instance directly from the management interface. Deregistration puts the instance into the unregistered state. You need to contact customer support team to do trust reset before you can reuse the NSM serial number. Then you can use the serial number to register the same or another instance. Only one NSM On-Premises instance is allowed per serial number. Be sure to delete the old, now unused VM.
