There's a risk / benefit tradeoff here; but it's quite possible to have SPOOL minidisks at second level with the same virtual VOLSERs as the real SPOOL volumes so that the, "look and feel" of the updated system is akin to the production system. It's not how I would have done it but it's perfectly feasible if it fits ones needs and strategies.
Myself, I've always tended to go for the, "copy the complete minidisk" strategy - maybe because I date back to the time when all maintenance was applied with a scalpel (and often very time-consuming) I've never fully trusted myself to unequivocally identify every file changed by an, "automatic" maintenance process.
