When performing Upgrading and Patching Validation, a validation error may occur in one of the following formats:
"Error Val0004 The component [1] contains the file [2]. This file is new to this component, but the key file for this component did not change. As a result, the new file will not get installed in an upgrade scenario. Include this file in a component whose key has changed, or place it in its own new component."
"Error Val0004 The file [2] in component [1] is different from the file in the previous package, but the key file for this component did not change. As a result, the changed file will not be installed in an upgrade scenario. Place this file in its own new component."
[1] is a placeholder that contains the component name that contains the new or changed file, while [2] contains the file name itself that is new or has been changed.
