Steps to take: Follow these steps:

For parmlib, add the data set pointed to by the z/OS V2R1 PARMLIB DDDEF to your parmlib concatenation. The data set should generally be added last in the concatenation, and you should make sure that the other data sets in the concatenation do not have members with the same names as IBM-supplied members. If you place the data set on the system residence volume and use an indirect catalog entry, future migrations will not require this particular migration step.
For proclib:
1. Ensure that the default proclib members have been copied to your default proclib to pick up the new and changed members.
2. Update individual sample members provided and ensure they are accessible to the system, as shown in the table of proclib member updates in z/OS Program Directory.
3. Ensure that the procedure libraries listed in the table of libraries to be added to the proclib concatenation in z/OS Program Directory are placed in the necessary procedure library concatenations and are available to the system.

Reference information: For lists of parmlib and proclib members that are shipped, see z/OS Program Directory at the z/OS installation related information website.
