If you are using data areas in the true sense of the word (One set of application programs, with several sets of data sharing those programs), how does the application upgrade process work?  In other words, do you have to run the upgrade programs for each data area?

Hmm can you clarify?

Our production productline has several data areas (setup that way awhile back because of security concerns with multiple companies sharing the same set of data). We only maintain one set of application executables, but 3 different data areas/databases. Understanding that you install the upgrade programs to the productline, would we have to run the upgrade programs for each data area?

Yes, you will need to. The upgrade program changes table structure also. So all your databases will need to be upgraded by the upgrade program.
