Normally the basis folks have a "cheat sheet" of things to do before and after system copies. Killing jobs, deactivating SCOT, etc should be on that list regardless of the network zoning, particularly if the ports for ALE and smpt are open.
Yes, I agree that whether or not the ports will be open at that point in time (still / again) depends on whether the effort and discipline involved fits the organization and possibly regulatory requirements (which I was not aware of).
Best rather not to have Credit Card data at all.. :-)
