Resetting the configuration
If you will be selling your FortiADC appliance, or if you are not sure what part of your configuration is causing a problem, you can reset it to its default settings and erase data. (If you have not updated the firmware, this is the same as resetting to the factory default settings.)
Important: Back up the configuration before performing a factory reset.
To delete your data from the system, connect to the CLI and enter this command:
execute formatlogdisk
To reset the configuration, connect to the CLI and enter this command:
execute factoryreset
