Reverting to a previous firmware version

System status

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

“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 your previous configuration
from the backup configuration file.

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.

4

Make sure the FortiGate unit can connect to the TFTP server.
You can use the following command to ping the computer running the TFTP server.
For example, if the TFTP server's IP address is 192.168.1.168:

execute ping 192.168.1.168

5

Enter the following command to copy the firmware image from the TFTP server to the
FortiGate unit:

execute restore image <name_str> <tftp_ipv4>

Where

<name_str>

is the name of the firmware image file and

<tftp_ip>

is the IP

address of the TFTP server. For example, if the firmware image file name is

FGT_300-v280-build158-FORTINET.out

and the IP address of the TFTP server

is 192.168.1.168, enter:

execute restore image FGT_300-v280-build158-FORTINET.out
192.168.1.168

The FortiGate unit responds with the message:

This operation will replace the current firmware version!
Do you want to continue? (y/n)

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 121

to make sure that antivirus

and attack definitions are up to date. You can also use the CLI command

execute

update_now

to update the antivirus and attack definitions.

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.
