version.
Reverting to a previous firmware version using the web-based
manager
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.
For information, see “Backing up and Restoring” on page 116 .
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.
To revert to a previous firmware version using the web-based manager
1 Copy the firmware image file to the management computer.
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.
