Step 3: Verify the upgrade
After the firmware image has uploaded to the FortiManager and the system successfully rebooted, login to the FortiManager system to verify that the upgrade has completed successfully.
To verify the upgrade:
1. Login to the FortiManager Web-based Manager using the previously configured administrator name and password. Also review all the administrator profiles to configure the proper access privileges.
2. Launch the Device Manager tab and make sure that all formerly added FortiOS v4.0 MR2 and v4.0 MR3 devices are still listed.
3. Launch other functional modules and make sure they work properly.
