Firmware upgrades

In addition to introducing the basics of upgrading FortiGate-7030E firmware, this section describes how to:
Upgrade the firmware running on individual FPCs.
l
Upgrade the management board firmware from the BIOS and reset the configuration of all of the FPCs.
l

Firmware upgrade basics

All of the FIMs and FPMs in your FortiGate-7000 system run the same firmware image. You upgrade the firmware from
the primary FIM GUI or CLI just as you would any FortiGate product.
You can perform a graceful firmware upgrade of a FortiGate-7000 FGCP HA cluster by enabling
upgrade and session-pickup . A graceful firmware upgrade only causes minimal traffic interruption. For more
information about graceful HA upgrades, see
Upgrading the firmware of a standalone FortiGate-7000, or FortiGate-7000 HA cluster with
upgrade disabled interrupts traffic because the firmware running on the FIMs and FPMs upgrades in one step. These
firmware upgrades should be done during a quiet time because traffic will be interrupted during the upgrade process.
A 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 factors such as the size of the configuration and whether an
upgrade of the DP2 processor 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.
l

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:

HA cluster firmware upgrades
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.
