We are running 8.0.1.2. We will be integrating Fedex shipping with realtime rates, including Smartpost. We want to use Fedex web services versus the API which I don't believe supports smartpost and is being phase out. Is the easiest way to do this upgrade to 8.0.1.4?

If we do upgrade does the license/upgrade require us to upgrade all aspects of the site or can we just implment the shipping changes?
