I hope a more pertinent response will appear, but I have Columbus Day off (thanks, Chris); and the mainframe still offers new worlds to explore.
At the very end of last year, we suddenly confronted an 'opportunity' to upgrade a z900 to z990. One image on that CEC had been stuck at z/OS 1.4 for some time. 1.4 was still supported then but was teetering on the edge of the support horizon. We had never installed z990 Exploitation Support because, well, we had never had one to exploit. With literally three weeks to prepare, we downloaded the package from ShopzSeries and installed it. It's important to remember that this is well aged code with lots of time in the barrel and so many tastings sampled by so many palates that new surprises are statistically unlikely. We ran the updated version for a while on the sandbox sysplex alongside a 1.7 image. No problems surfaced. The more important question of whether you can get your hands on the z990 package has to be explored. The package I got had some FMIDs that I didn't need; don't remember the details. Just a long SMP/E job. As a historical footnote, I have to add that the application holding back the 1.4 image got heroically upgraded in time for the upgrade so we never had to run the 1.4 code in production. I also need to yellow hilite the upgrade to z990, not z9. So this is a little like CC's finding America on the way to India. If his sponsors had been truly desperate for tea and curry, the poor boy would have been disgraced and thrown into prison. Hmm. We all wish you a better outcome. . .

It looked like you just had to apply the appropriate compatibility PTFs and PSP buckets. However, I either did not see or missed if this was done using the ORDERABLE comparability functions while z/OS 1.4 was still supported. The only way now is to download the z990 Exploitation Support for z/OS V1.4 from the web. This has the compatibility functions bundled in with other exploitation changes (which I don't really need). Has anyone used this method to get there operating system ready for a new machine, and if so how bad was the maintenance process. We don't have to run the z/OS 1.4 image for long on the new machine but we have a push pull machine change so have to feel comfortable about image coming up. It is also part of an existing SYSPlex contained on the one machine ( the others being z/OS 1.7 so only PSP bucket fixes for them), don't know if that complicates matters or not. ---------------------------------------------------------------------- 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
