I am not at all an expert on Sysplex compatibility. I bring to the table only the knowledge of the IBM policy and years of experience with "how things work."
I think the answer is very simple: it might work and it might not. Or, more correctly, it might IPL, and if it does, then everything YOU care about might work, or on the other hand something might not work. You have three requirements: - z/OS 1.13 - z/OS 2.3 - Implicitly, mainframe-level quality of service One of those has to go. Pick one. I would pick 2.3 as the one to go -- you may *think* you need it, but I am going to guess you don't need it, you want it. And if management insists that 2.3 is not the one to go, then mainframe quality of service is going to be the one to go, because SOMETHING has to go. When JES2 or RESERVE or whatever breaks, what the heck are you going to do? I'm just re-phrasing what @Mark says below.
