IEBCOPY can be used to totally or partially copy a partitioned data set from one direct access volume to another. In addition, a data set can be copied to its own volume, provided its data set name is changed. (If the data set name is not changed, IEBCOPY interprets the request as a compress-in-place, provided the SELECT / EXCLUDE statement is not coded.)

When you use IEBCOPY to copy a PDSE to a PDSE, either volume to volume or to its own volume, all DDM attributes are also copied.

Members copied into a partitioned data set are not physically reordered; members are copied in the physical order in which they occur in the original data set.
