To gracefully decommission a vNIOS server, the ideal step is to reset all the data on the server. If you require any data/logs from the server for record purposes, make sure to download the relevant data before decommissioning the server.
To reset the data, 'reset all licenses' command can be issued from the CLI which resets the server database, deletes all licenses and log files, and also reset the network settings to factory default values.
