Downgrading to FortiOS v2.80MR11 using web-based manager

Downgrading to FortiOS v2.80MR11 using the CLI

Use the following procedure to downgrade to FortiOS v2.80MR11 in the CLI. If you have created additional settings in FortiOS 3.0, make sure you back up your configuration before downgrading. See “Backing up your FortiOS 3.0 configuration” on page 37 for more information.

To downgrade using the CLI

1Make sure the TFTP server is running.

2Copy the firmware image file to the root directory of the TFTP server.

3Log into the FortiGate CLI.

4Make 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

5Enter the following command to copy the firmware image from the TFTP server to the FortiGate unit:

execute restore image tftp <name_str> <tftp_ipv4>

Where <name_str> is the name of the firmware image file and <tftp_ipv4> is the IP address of the TFTP server. For example, if the firmware image file name is image.out and the IP address of the TFTP server er is 192.168.1.168, enter:

execute restore image tftp image.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)

6Type y.

The FortiGate unit uploads the firmware image file. After the file uploads, a message similar to the following is displayed:

Get image from tftp server OK. Check image OK.

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

7Type y.

The FortiGate unit reverts to the old firmware version, resets the configuration to factory defaults, and restarts. This process takes a few minutes.

After the FortiGate unit uploads the firmware, you will need to reconfigure your IP address since the FortiGate unit reverts to default settings, including its default IP address. See your install guide for configuring IP addresses.

8Reconnect to the CLI.

9To confirm the new firmware image has been loaded, enter: get system status

See “Restoring your configuration” on page 40 to restore you FortiOS v2.80MR11 configuration settings.
