Converting Partitioned Data Sets to PDSEs

You can use IEBCOPY to convert partitioned data sets to PDSEs.

To convert a partitioned data set to a PDSE, create a PDSE and copy the partitioned data set into the new PDSE. This can be accomplished with one use of IEBCOPY.

You cannot convert a partitioned data set that has any of the following features:

Both load modules and nonload modules in the same partitioned data set. Individual members of a partitioned data set can be converted by copying them into two separate PDSEs, the first for data and the second for program objects.
Note lists. Load modules that contain note lists can be placed into PDSEs because they are converted automatically into program objects.
Nonzero key lengths in the members.
