CVTPFRDTA and CVTPFRCOL command changes

The Convert Performance Data (CVTPFRDTA) and Convert Performance Collection (CVTPFRCOL) commands no longer support in-place file conversions.

The Convert Performance Data (CVTPFRDTA) and Convert Performance Collection (CVTPFRCOL) commands no longer support in-place file conversions (where the from library and to library are the same). In-place conversions have always been discouraged and are not always possible. Due to the increasing complexity of collections, only conversion to a different library will be supported so that the result can be verified without losing the original data.
