Just in our latest upgrade from 2.1 to 2.3, we were recommended by various ISVs to apply service or even upgrade to a higher release. We mostly did as directed but in a few cases demurred. In some of those cases we got away with that, in other cases burned.
I would never advise hoping to gliding on through. Too much changes from OS release to release. . .

Don't know about most, but ALL seems highly unlikely. I can state with certainty that *every one* of the z/OS-based products we run here from other ISVs would need to be upgraded (or at least have all service applied if still supported) as would several of our own. My recommendation, especially for shops with a tendency to fall way behind like this one has, is to bite the bullet and upgrade to the "latest and greatest" release of everything possible whenever the opportunity presents itself. Running old, unsupported code on a new operating system is just asking for trouble. And, who knows how long it might be before you get another chance to upgrade? -- Phoenix Software International Edward E.
