We are in the same situation (on 1.9 and want to get to 1.12). After some research I found that there was really no compat maintenance from 1.11 to 1.12, so we just put on the compat maint for 1.9 to 1.10 and 1.9 to 1.11 and we're currently trying the upgrade to 1.12. So far there have been no issues and with our simple setup I think we should be fine.
We are also a simple monoplex. I would probably not try this upgrade if we were any kind of multi-system sysplex. C.

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?": http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/e0z2b1b0/3.1?SHELF=EZ2ZBK0K&DT=20100701181224 -- John Eells z/OS Technical Marketing IBM Poughkeepsie [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
