....and it might help to look at it in terms of a product line. Using two products as an example:
Prod1 v1.0 => Prod1 v2.0 => Prod1 => v3.0 And Prod2 v10.0 => Prod2 v11.0 => Prod2 => v12.0 Each of these is a product line where each new version is intended to replace any already-installed pre-existing versions. Prod1 and Prod2 would each have their own unique UpgradeId for the life of the product although each version would have a new ProductCode. The point is that Windows makes it easy to do the upgrades because all you do is use the Upgrade table to say which previous versions you want to upgrade. You get the uninstall/upgrade for free with RemoveExistingProducts.

It appears that it is something independent of the product code - which means that we could leave the upgrade GUID the same for a variety of versions which means "uninstall anything w/ this upgrade code". Or, does it mean that we can specify all known product GUIDs of all installers we have built and release, to say "remove them before installing"?
