execute : execute restore image
 
execute restore image
Use this command to install firmware on the primary partition and reboot.
 
Back up the configuration before installing new firmware. Installing new firmware can change default settings and reset settings that are incompatible with the new version.
Unlike installing firmware via TFTP during a boot interrupt, installing firmware using this command will attempt to preserve settings and files, and not necessarily restore the FortiADC appliance to its firmware/factory default configuration.
Syntax
execute restore image tftp <filename> <ip>
<filename>
Name of the firmware image file.
<ip>
IP address of the TFTP server.
Example
This example installs a firmware file named firmware.out from the TFTP server, 192.168.1.23, to the FortiADC appliance.
FortiADC-VM # execute restore image tftp firmware.out 192.168.1.23
This operation will replace the current firmware version!
Do you want to continue? (y/n)
The FortiADC appliance downloads the firmware file, installs it, and reboots.
