Device Manager : Managing devices : Replacing a managed device : Changing the serial number from the CLI
 
Changing the serial number from the CLI
If the device serial number was entered incorrectly using the Add Model Device wizard, you can replace the serial number from the CLI only. Use the command:
execute device replace <device name> <serial number>
This command is also useful when performing an RMA replacement.
