I connection with possible problems from "moved" VTAMLST members, I used to do the following:

But first I need to explain the environment. I used to have a number of test MVS systems running on the same VM system. There was also a "production" MVS system also running on the same VM system from which I could access all the volumes used to support the test systems.

I was very often playing around with VTAM and making very frequent changes to VTAMLST members - as one does with test systems. Whenever I felt I may be getting near to the capacity of a VTAMLST data set, I ran a "z" on it from a TSO ISPF session running in the production MVS system. I was actually somewhat paranoid about running out of space so I probably "z"ed far more often than I really needed to.

I recall having no problems ever - in getting on for 20 years - over a "moved" VTAMLST member.

You can compress the dataset in batch with IEBCOPY and DISP=SHR but you
run the risk of active tasks having problems if any open member is
relocated.
