I never did it except in sandbox environments and usually wait a couple of releases for changing things like that, but never did it in production. The problem is homegrown code that may be floating around in production environments that you don't know about. I'm often surprised about the kinds of things I discover running as part of batch jobs when some need to research a problem comes up. You can also move the LCCA and PCCA above the line via CBLOC in DIAGxx. That was introduced in z/OS 1.9 and the default in z/OS 1.12, so you should be running with it. ASVT option was in z/OS 2.1 and still isn't above by default (maybe z/OS 3.1? I haven't looked). All my sandbox LPARs have this coded and I'm sure system software is all fine since z/OS 2.3. I think I added ASVT even in z/OS 2.1 in my sandboxes after all software had z/OS 2.1 maintenance or versions running.
