Reverting to a previous firmware version Managing firmware versions

Verifying the downgrade

After successfully downgrading to FortiLog 1.6, verify your connections and settings. If you are unable to connect to the web-based manager, make sure your administration access settings and internal network IP address are correct. The downgrade may change your configuration settings to default settings.

Downgrading to FortiLog 1.6 using the CLI

The following procedure enables you to downgrade to FortiLog 1.6 in the CLI. If you have created additional settings in FortiAnalyzer 3.0, make sure you back up your configuration before downgrading. See “Backing up your configuration” on page 169 for more information.

To downgrade using the CLI

1Copy the new firmware image file to the root directory of the TFTP server.

2Start the TFTP server.

3Log into the CLI.

4Enter the following command to ping the computer running the TFTP server: execute ping <server_ipaddress>

Pinging the computer running the TFTP server verifies that the FortiAnalyzer unit and TFTP server are successfully connected.

5Enter the following command to copy the firmware image from the TFTP server to the FortiAnalyzer 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 FortiAnalyzer unit responds with the message:

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

6Type y.

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

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