The statement 'As far as you use version R80.40, no upgrade is needed due to compatibility mode' is false. When the management server is upgraded to a new major version like R81.10, an upgrade to the SmartConsole is required to ensure compatibility and access to the latest features and fixes. The other statements are true: you can download SmartConsole from the Download Center, the installer can be made available via CPUSE in the Web Portal, and the SmartConsole Upgrade package can be installed using CPUSE.
