Use the following procedure to convert an alter-type work ID to a CDL file. The CDL that results acts as a record of changes to the data structures.
You can also use the resulting CDL to transmit those changes to another local subsystem or to transmit inter-version changes to remote subsystems.
Where to go from here
After you have compared your data structures and have generated a CDL file, you can import the CDL file to an alter-type work ID on the same or on a different Db2 subsystem and process it as a set of change requests for a subsystem.
