Component GUIDs (Component/@Guid attribute) are a global identifiers (the "G" and the "ID" in GUID). Products take reference counts on those GUIDs. So, Component GUIDs are vitally important in upgrades.
The Component "name" (Component/@Id attribute) is scoped to an .MSI file and changing it really only has implications to patching (due to the way patching is implemented).

That and the preceding article were informative, I appreciate that. While reading those and a few MSDN articles that your articles referred to, I still don't know the semantics around product upgrades. Do component IDs (the GUID) matter between product upgrades?
Or in that case, does just the component name matter?
Thanks a lot,
