Using an IDCAMS REPRO utility to copy the Control File is not recommended because it can cause unpredictable results. Instead we recommend either:
1) Using the Control File, Datastore & Profiles from the prior release with the new release. (Note: Datastores that
were created before r15 & Profiles that were created before r14 cannot be used with this method).
2) Allocate a Control File, Datastore & Profiles for the new release. Afterwards, copy the Old Datastore & Profiles
into the new ones using the PDTDSCPY & PDTCPCPY Utility jobs in the <High.Level>.CDBASRC library.
