IBM has actually made adjustments so some times it works out that you will
see a cost savings going to the newer hardware
we definitely saw that here by going to our Z/10

I'm not sure where that comes from, Wayne. We're not forcing anyone to
upgrade anything. There are still people out there running VM/ESA on
their 9672s. If they wanted to run z/VM on their 9672, they would have
gotten z/VM V3 or V4. But apparently they are content with the status
quo. Sure, it's a business risk to run in configurations that your
h/w-s/w vendor won't support, but that's nothing new.
Time does march on, though, and the technology changes. 360 -> 370 ->
370/XA -> 390 -> z. For 5 releases and 5 years (z/VM 3.1 through z/VM
4.4), we straddled the S/390 - z/Architecture fence. Then we jumped onto
z with both feet with z/VM V5. Since 2001 we have not been able to
exploit new instructions in z/VM, but as of z/VM 6.1, we have.
People who want to stay on a pre-z10 z/Architecture box can do so. z/VM
5.4 remains orderable concurrently with z/VM 6.1 and has had its
end-of-service date moved to 9/30/2013.
