So the OS between the two servers is still RedHat, just the difference between 32 bit and 64 bit, correct? Are they the same release, same glibc, same kernel?
It doesn't surprise me that it would work as Universe on RedHat is 32 bit, not 64, but I wanted to get more details if possible.

I'm not going to be able to do any testing further in depth because we need to reallocate the qlogic cards, unfortunately, but at least in a trivial way it worked absolutely fine. System came up and all the custom software I tested worked exactly as expected. Many thanks, Mike & all, this is heartening.
