DB2 Universal Database Quick Beginnings for Windows provides information about how the active warehouse control database is migrated during a typical install of DB2 Universal Database Version 7 on Windows NT and Windows 2000. If you have more than one warehouse control database to be migrated, you must use the Warehouse Control Database Management window to migrate the additional databases. Only one warehouse control database can be active at a time. If the last database that you migrate is not the one that you intend to use when you next log on to the Data Warehouse Center, you must use the Warehouse Control Database Management window to register the database that you intend to use.
