Firmware upgrade basics

All of the FIMs and FPMs in your FortiGate-7000 system run the same firmware image. You upgrade the firmware using
the primary FIM GUI or CLI just as you would any FortiGate product. During the upgrade process, the firmware running
on all of the FIMs and FPMs upgrades in one step. Firmware upgrades should be done during a quiet time because
traffic will be briefly interrupted by the upgrade process. The entire firmware upgrade takes a few minutes. depending
on the number of FIMs and FPMs in your FortiGate-7000 system. Some firmware upgrades may take longer depending
on other factors, such as the size of the configuration and whether a DP processor firmware upgrade is included.
Before beginning a firmware upgrade, Fortinet recommends that you perform the following tasks:
Review the latest release notes for the firmware version that you are upgrading to.
l
Verify the recommended upgrade path as documented in the release notes.
l
Back up your FortiGate-7000 configuration.

Verifying that a firmware upgrade is successful

After a FortiGate-7000 firmware upgrade, you should verify that all of the FIMs and FPMs have been successfully
upgraded to the new firmware version.
After the firmware upgrade appears to be complete:
1. Log into the primary FIM and verify that it is running the expected firmware version.
You can verify the firmware version running on the primary FIM from the System Information dashboard widget or
by using the get system status command.
2. Confirm that the FortiGate-7000 is synchronized.
FortiGate-7040E System Guide
Fortinet recommends that you review the services provided by your FortiGate-7000 before a
firmware upgrade and then again after the upgrade to make sure the services continues to
operate normally. For example, you might want to verify that you can successfully access an
important server used by your organization before the upgrade and make sure that you can
still reach the server after the upgrade, and performance is comparable. You can also take a
snapshot of key performance indicators (for example, number of sessions, CPU usage, and
memory usage) before the upgrade and verify that you see comparable performance after the
upgrade.
