Adding an additional data frame manager

10.2.1 is the final release in which MPS-Atlas is available for installation. It is recommended that map series created with MPS-Atlas be moved to data driven pages. For more information, see Migrating an MPS-Atlas map book to Data Driven Pages.
A map series' shared map sheet contains the layout used for all the shared maps in the series. When creating a new map series, you can add new data frames to the map sheet and then add a corresponding data frame manager to define the properties of the new data frame.
