Procedure
Step 1 Upload system software packages to the two FWs respectively.
Step 2 Run the shutdown command to disable the service and heartbeat interfaces of FW_B
(standby device). You must run the shutdown command to disable the service interface first
and then the heartbeat interface. You can run the shutdown command to disable the heartbeat
interface of FW_B but not that of FW_A.

NOTE
Upgrade the standby FW first. Before the upgrade, run the shutdown command to
disable the service and heartbeat interfaces of the standby FW to isolate the standby FW.
After the standby FW is upgraded, run the shutdown command to disable the service
and heartbeat interfaces of the active FW to isolate the active FW. Then run the undo
shutdown command to enable the heartbeat and service interfaces of the standby FW
and switch service traffic to the standby FW for forwarding.
Upgrade the active FW.
After the active FW is upgraded, run the undo shutdown command to enable the
heartbeat interface first. After the heartbeat interface becomes Up, synchronize session
entries between the active and standby FWs. After the session entries are synchronized,
run the undo shutdown command to enable the service interface. It takes around two
minutes to synchronize the entries.
Verify whether services are normal after the upgrade. Perform the active/standby
switchover test.
