Reverting to a previous firmware version
Use the following procedure to revert your FortiGate unit to a previous firmware version.
This also reverts the FortiGate unit to its factory default configuration and deletes IPS
custom signatures, web content lists, email filtering lists, and changes to replacement
messages. Back up your FortiGate unit configuration to preserve this information. For
information, see “About the Maintenance menu” on page 311.
If you are reverting to a previous FortiOS™ version (for example, reverting from FortiOS
v3.0 to FortiOS v2.8), you might not be able to restore the previous configuration from the
backup configuration file.
To revert to a previous firmware version using the web-based manager
1 Copy the firmware image file to your management computer.
The firmware images for FortiGate units are available at the Fortinet Support web site.
2 Log into the web-based manager as the super admin, or an administrator account that
has system configuration read and write privileges.

a few minutes.
7 Log into the web-based manager.

For information about restoring your configuration, see “About the Maintenance menu”

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 329 to
make sure that antivirus and attack definitions are up to date.
