Merging data

If you have an application that is currently running on independent Db2 subsystems, you might decide that the application will work well in a data sharing group.

In that case, you must move the data and merge the catalog definitions for that data from the independent Db2 subsystems into the data sharing group. Because the Db2 subsystems still exist, you cannot reuse their subsystem names when installing the subsystems as new members into the data sharing group.

Db2 does not provide an automated way to move catalog definitions from an independent Db2 subsystem into the catalog of the data sharing group. If you have procedures and tools to move applications from test to production, or to handle merging databases from enterprise reorganizations or mergers, those same procedures can be used to move applications into the data sharing group.
