I'm with Jazz on this, don't upgrade when you don't really need to. It'll cause more problems than its worth.

You don't have to airgap it. Personally, I'd take a half-way house approach; I'd firewall it at the router, completely blocking internet traffic in and out to that specific machine. This way, you can still transfer things to it within the network. Its not as secure as total air gap, but honestly its more than effective enough if you're not hiding sensitive documents.
