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
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.
.
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.
!
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.
