Run this procedure after a system expansion to rename the temporary, planned maps created with the CreateExpansionMaps procedure to the actual maps to be used in the Mover procedures. This procedure removes the prefix PreExpansionMap before the map names. This procedure is necessary if you ran the Advisor procedures before the system expansion and are not going to run them again afterward.
