Managing firmware versions

Before upgrading to FortiAnalyzer 3.0, it is recommended to review this chapter so you can be fully aware of the procedures and issues when upgrading to FortiAnalyzer 3.0. This chapter includes upgrading issues for all FortiAnalyzer 3.0 firmware versions and how to revert back to a previous firmware version, either to FortiLog 1.6 or an earlier FortiAnalyzer 3.0 firmware version.

In addition to firmware images, Fortinet releases patch releases–maintenance release builds that resolve important issues. Fortinet strongly recommends reviewing the release notes for the patch release before upgrading the firmware. Follow the steps below:

download and review the release notes for the patch release

download the patch release

back up the current configuration

install the patch release using the procedure “Testing firmware before upgrading” on page 172

test the patch release until you are satisfied that it applies to your configuration

Installing a patch release without reviewing release notes or testing the firmware may result in changes to settings or unexpected issues.

This chapter includes the following sections:

Backing up your configuration

Testing firmware before upgrading

Upgrading your FortiAnalyzer unit

Restoring your configuration

Reverting to a previous firmware version

Note: Fortinet recommends upgrading the FortiAnalyzer unit during a low traffic period, for example at night, to re-index log data. Generating reports before the log index is complete results in incorrect data in reports. The FortiAnalyzer unit will take time to complete the index if there is a lot of log data. You can verify that the indexing is complete by viewing the Alert Message console on the Dashboard.

Backing up your configuration

Fortinet recommends backing up all configuration settings from your FortiAnalyzer unit before upgrading to FortiAnalyzer 3.0. This ensures all configuration settings are not lost if you require downgrading to FortiLog 1.6 and want to restore those configuration settings.

Caution: Always backup your configuration before installing a patch release,

upgrading/downgrading, or when resetting to factory defaults.

 

Always back up log data before upgrading/downgrading.
