We too: we moved our z/VM 4.4 31-bit mode from 9672 onto z9, then stepped
right to z/VM 5.2 in 64-bit mode.

Tom--That doesn't match what I remember from when we first got the z9.
I think that we, initially, ran with the 31 bit nuc on the z9.  We are
running 4.4, now, with the 64 bit option.  Until recently, I ran my 2nd
level test 4.4 system using the 31 bit nuc under a 4.4 nuc running with
the 64 bit nuc.
