Short version... We are running z/OS 1.9 and do not have a 1.10 or 1.11 system
to install. I'd like to install a 1.12 Serverpac on the road back to being
supported. I know about the n+2 rule but how do I get out of this pickle? I'm
not talking about toleration and coexistence, just a driving system to install
1.12. We are a pretty simple monoplex.
Shopz has a driving system that can be ordered. Is this a good approach?
I would like to use our 1.9 system to install 1.12. The 1.12 doc says you must
have at least 1.10. Does anyone know if 1.9 will work for the Serverpac install?
Are there any other options that I may not know about? (of course, it can't
cost a lot of money ;)

z/OS R10 is the lowest supported release of z/OS, at least for a few
more months. While z/OS R9 might or might not work for installing z/OS
R12, we didn't test it and won't support it if there is a problem.
It would be safest to order a Customized Offerings Driver (5751-COD),
IPL it in a test LPAR, and use it to install R12. Having a system
available that meets the driving system requirements for the current
release is one of the two reasons we have a COD. If you intend to try
installing R12 using R9, you might consider ordering the COD as a
backup, so if there is a problem you won't have to wait for another
order. The price is right (there is no additional charge if you have a
z/OS license).
Current information on the COD is in z/OS Planning for Installation
topic 3.1, "What is the Customized Offerings Driver?":
