After a system expansion, there are 2 contiguous maps: the old map without the new nodes and associated AMPs and the new map with the new resources. After all the tables and databases are reassigned to the new map, drop the older contiguous map (the default is TD_Map1) using a DROP MAP request to prevent accidental use of this old map.
