It is unlikely to be *NECESSARY* to apply the z10 maint to the z/OS 1.7 systems. IMO, it is highly desirable to do so! One of the design points for a parallel sysplex was to allow for just that situation, but what if some PHB decides to move the LPARs around? One of the rules I have always followed in my multi-system career, is that everything should be the same, except where required to be different. Another rule I have followed is to routinely apply device support and toleration/fallback maintenance as it becomes available (even if I don't plan to go to that release). When the new box (or OS) rolls in, there is nothing to do except load and go!
