Regarding machine replacement, if you get newer model OSA's you may change from one chpid per port to one chpid per port pair, which will force you to modify your definitions in z/VM to point to the correct OSA Port in addition to the correct memory range.
Not a big deal, but an owie if you miss it.

NPIV I guess was explained already (we actually implemented NPIV and SAN after we moved to z114). I would only suggest downloading and applying PTFs for z/vm. There were some pdfs from IBM which specify which PTFs you have to have in your z/vm 5.4 for z114. There aren't many but still, you should check this out. You will have to slightly adjust your IOCP because some chpids changed in z114. There are tools out there to remap those but for us, IBM guy did it before we plugged in new machine. Guys who were setting up z114, moved all LPARs configurations and uploaded new iocp. Generally in our case it all went smooth and after 2hours we were up again.
