Relying on the installer's file replacement rules, do a major upgrade with RemoveExistingProducts right at the end of your execute sequence as InstallExecute, RemoveExistingProducts, InstallFinalize. The incoming Xml file will replace the old one only if it's not been updated (file replacement rules for neither file has a version creation date vs modify date) and leave behind the older modified one.
