We are planning to upgrade to z/VM 7.2 in the near future. I found fix SO14588 for VM:Tape.
Can this be applied prior to the upgrade without affecting our tape processing as it is today on a 6.4 or a 7.1 system?
Release : 2.0
Component : CA VM:Tape for zVM
Yes, the PTF can be applied and deployed to VM:Tape prior to the z/VM upgrade.
