Bill - We have been for years upgrading yearly with z/OS. We order in Sept install on lab system we have setup. Then roll out in March of the following year. One of the benefits we noticed for example is when we have brought in new hardware. For example, going to the new CPU or VTS we don't have to do much or put on much maintenance to support these things as they happen. Also upgrading year after year IBM doesn't make major release changes which affect our users. This makes it an easier conversation with the change management team and gets dates for testing and roll out. It has been a challenge with other technical units, sometimes they have problems keeping up with us but has delayed a roll out or two a few years back before we started doing it this way.
On a side note we also install an RSU each month and that too has helped, we feel because of it we haven't experienced a sev one outage (knock on wood) in over 10+ years in our production environment, not to say in test we haven't ;) Andy S.
