Basically the same functionality as an <Upgrade/> element.
How do you do that from a merge module?
You can't control upgrades from a merge module: That's the
responsibility of a product, not its constituents. However, if you
follow component rules with stable component IDs and GUIDs, you get the
above behavior "for free." MSI tracks components and will do nothing for
each component that's already installed.
