I believe another question to ask is what are the applications running on this system. I worked on a Realtime Tracking system using MVT and then MVS where they had used many of the IBM "spare" control block fields for things. In that case it was ugly to upgrade. If the applications are just everyday code, then there is a possibility for upward compatibility. It can't be too custom if they are accepting a date back in 1990's and probably postprocessing everything to get it current.
Sounds like an interesting challenge.
