The FortiGate unit uploads the firmware image file, upgrades to the new firmware 
version, and restarts. This process takes a few minutes.

Reconnect to the CLI.

To confirm that the new firmware image is successfully installed, enter:
get system status

Use the procedure 

 to update 

antivirus and attack definitions, or from the CLI, enter:
execute update_now

Use the following procedures to revert your FortiGate unit to a previous firmware 
version.

The following procedures revert the FortiGate unit to its factory default configuration 
and deletes IPS custom signatures, web content lists, email filtering lists, and changes 
to replacement messages.

Before beginning this procedure you can:

• Back up the FortiGate unit configuration. 
• Back up the IPS custom signatures. 
• Back up web content and email filtering lists.

If you are reverting to a previous FortiOS version (for example, reverting from FortiOS 
v2.80 to FortiOS v2.50), you might not be able to restore the previous configuration 
from the backup configuration file.

Copy the firmware image file to the management computer.

Log into the FortiGate web-based manager.

Go to System > Status.

Under Unit Information > Firmware Version, select Update.

Type the path and filename of the firmware image file, or select Browse and locate the 
file.

Note: Installing firmware replaces the current antivirus and attack definitions with the definitions 
included with the firmware release that you are installing. After you install new firmware, use the 
procedure 

 to make sure that antivirus 

and attack definitions are up to date.

Note: To use this procedure you must login using the admin administrator account, or an 
administrator account that has system configuration read and write privileges.
