Table 1: Firmware upgrade procedures
Procedure Description
Upgrading to a new
firmware version Use the web-based manager or CLI procedure to upgrade to a new
FortiOS firmware version or to a more recent build of the same
firmware version.
Reverting to a
previous firmware
version Use the web-based manager or CLI procedure to revert to a
previous firmware version. This procedure reverts the FortiGate
unit to its factory default configuration.
Installing firmware
images from a system
reboot using the CLI Use this procedure to install a new firmware version or revert to a
previous firmware version. To use this procedure you must connect
to the CLI using the FortiGate console port and a null-modem
cable. This procedure reverts the FortiGate unit to its factory
default configuration.
Testing a new
firmware image before
installing it Use this procedure to test a new firmware image before installing it.
To use this procedure you must connect to the CLI using the
FortiGate console port and a null-modem cable. This procedure
temporarily installs a new firmware image using your current
configuration. You can test the firmware image before installing it
permanently. If the firmware image works correctly you can use
one of the other procedures listed in this table to install it
permanently.
Installing and using a
backup firmware
image If the FortiGate unit is running BIOS version v3.x, you can install a
backup firmware image. Once the backup firmware image is
installed you can switch to this backup image when required.
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 update antivirus and attack definitions” on page 120 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.
