Thank-you all for your responses. Again the IBM-Main community shows it's
strength.
I think I'll be sticking with ECS at the moment.
Much appreciated,

Agreed, way too much risk. We don’t swap master cat's at all either. No
reason to, except maybe those shops that cannot fit the entire SYSRES on one
volume, so you have the issue where DSN A is cataloged on the first volume of
the set pre-upgrade, and post-upgrade

By using INDIRECT CATALOG you can use different SYSRES Sets, but the same
