With Web Connection 6 and 7 having moved to clearly separate your projects from the Web Connection installation, the guidelines for updating Web Connection applications have changed a bit and have become a lot simpler.

Check out the updated documentation in the Docs that also shows how to update your projects using the new UpdateProjectResources
support features both as a Console Applet and via the Console command line.
