I tend to agree that system replacement can be quite a bit faster than upgrade, but having done this several times in the past two years I think 1 month is reasonable which includes planning to cut-over implementation for a replacement. Upgrading can be a whole different animal because there can (and will) be a number of exits and other site specific items which have to be altered. Most exits will have no problem at all, but you still have to check them all. I have also come to believe that there is no such thing as a "vanilla" z/OS shop.
Just being a systems programmer, even a very good one, doesn't mean that you have installed z/OS, or that you can handle the conversion. That's one of the reasons that consultants are still in such demand. When it comes to upgrading, nothing beats experience.
