An old customer has just called saying they're buying a z9BC, upgrading from
a z890 and could I pop along to move them over. They're currently running
zOS 1.6 (guest of zVM with other VSE and zLinux guests) and would preferably
like to stay on the 1.6 system. I know that since I installed it a couple of
years back that no maintenance has been installed or any PTFs or anything in
fact. The system has no users as its only used for EE. After reading the
literature it seems that 1.6 is okay to go on the z9BC, all I would have to
do is install the 2096DEVICE PSP. Am I correct in this thinking? Or should I
do my utmost to convince them to go 1.8 for peace of mind?

Seb,
We went from a z/OS 1.6 Flex box to a z9 box. The option of moving to
the new box could have included a move to 1.8 as well. We opted for
fewest changes possible. We knew 1.6 worked, and how well it worked.
If things didn't work right on the new box, we could focus on getting
1.6 to work with the new box. If we had gone to 1.8 during this
transition, we would be left wondering if the problem were the new box,
or the new OS.
1.8 is in our future.
It's a cautious approach that I recommend. It should also give you
better peace of mind.
