Reverting to a previous firmware version using the CLI

This procedure 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.
Before beginning this procedure you can:
• Back up the FortiGate unit system configuration using the command execute

backup config.

• Back up the IPS custom signatures using the command execute backup
ipsuserdefsig
• Back up web content and email filtering lists.
For information, see
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 your previous configuration
from the backup configuration 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 update antivirus and attack definitions" on page 123
and attack definitions are up to date. You can also use the CLI command
update_now to update the antivirus and attack definitions.
To use the following procedure you must have a TFTP server that the FortiGate unit
can connect to.
To revert to a previous firmware version using the CLI
1 Make sure that the TFTP server is running.
2 Copy the firmware image file to the root directory of the TFTP server.
3 Log into the FortiGate CLI.
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.
