Re: This makes me sad
HPUX on x86? Why? We've managed to move enormous amounts of code from HPUX to linux on x86 with only moderate lifting. Hell, I picked up an entire MF app in java and moved it over without a hiccup, no changes needed. Mind you, the java is ancient and getting the app owners to let me advance the version to something approaching supported is somewhat painful, but progress was made.
Cobol stuff needed some twiddling but recompiled well. License cost was stupid, at first, but when told what we were doing, the licensing became more rational. C code based stuff was a sweep and tidy on includes mostly and away we went (mind you the C stuff on hpux was originally compiled with gcc from the external depots)
HPUX on Itanium has its place - and you wont get the speeds out of x86_64 without *almost* the same investment in $$ worth of hardware, and floor space, but it still works in certain cases.
