And I responded with an example. A 10gR2 RAC cluster running on RedHat 3 in test with the Grid OMA will not work with RedHat 4.

But why say: "other than bugs?" Isn't that 99% of the reason not to do so?

Exactly. It needs to be tested. So how can you have different versions in test and prod? Signing off on "my app works in Solaris 2.8 so therefore it will work in Solaris 2.10 is insane." It might work beautifully ... it might also crash and burn.
