1) Is dev/test/prod on same LPAR? Yes and No
2) Is dev/test/prod on same box? Yes and No
Having the systems COMPLETELY separated from each other is the best (my opinion for what it's worth).
This way, when the Dev data is COMPLETELY demolished, a person saying "Oops, I didn't mean for THAT to happen" doesn't give you palpitations
3) How frequently are promotions from dev to test allowed? A). No restrictions, however, there are certain times when users are in the system that would make it difficult for them to get off while your promotion lasting 17 hours will stop them working. So scheduling for overnight, weekends, holidays etc. maybe required
a. No restrictions
b. Daily
c. Weekly
d. Other
4) Does separating DEV from TEST require more time & effort for a given development project? Compared to what?
I'm not being facetious or flippant, but this is a genuine question.
We tend to copy the data from the production system that was applied in the last 3 months to the dev system.
5) What would be some reasons why this is a good idea (besides the auditors told us to)?
See the answers to 1 and 2

Thanks!
