That may not be true. We brought up z/OS 1.4 in production on our 9672
R16 before going to our z/890. z/OS 1.4 runs in 31-bit mode on the
9672, but it does depend on the model of 9672. We did have to put on
the bi-modal patch so that we would still be 31-bit on the z/890. Once
we tested out 64-bit over there, we turned on 64-bit mode in
production. Our migration went like this:
OS/390 2.10 to z/OS 1.4(31-bit)
9672-R16 to z/890 240 with z/OS 1.4(31-bit)
z/OS 1.4(31-bit) to z/OS 1.4(64-bit)

Thomas/Paolo,
This is very strange. We've been told by IBM that inorder run anything
higher than OS/390 2.10, we had to go to a z box. We're currently running
OS/390 2.6 on a 9672 R83.
