The products we're contemplating "moving" (RDz and WAS) are rather intimately
intertwined with Language Environment (LE), which is a part of base z/OS. The
motivation behind our contemplated "move/merger" is to facilitate our
recognition and resolution of cross-zone IFREQs and COREQs between the products
and LE.

Since that process should remain substantially unchanged in the future, having
done it once should allow us to declare it nearly an exact science. :-)

Thanks for your valuable insights. Keeping our z/OS 1.13 Global zone
"pristine" would still require us to create product-specific Global zones (and
CSI datasets) in order to "de-link" them from the z/OS 1.11 Global zone,
wouldn't it? If so, the original questions and considerations regarding
"moving" products from one Global zone to another remain.
Thanks,
