Hello, Does anyone know if the project wbs GUIS should match it's baseline wbs GUID?

Our P6 project wbs guid is not the same for the baseline wbs guid.  The activity GUID  matches between project and baseline but I'm find none of the wbs guid values match.  I'm trying to link the baseline WBS back to the project WBS for a comparision. Do you have a suggestion on how to accomplish if we can't use the GUID?

Thanks in advance!
