It's been a long time, but I believe not. We used to run a 
mixed-architecture cluster using the same PH code for both systems.
It works because it isn't really native executable code, but just tags 
to be interpreted by the quiz/quick/qtp images.

You'll obviously have to install the exact same version of powerhouse.

Any 3gl code *WILL* have to be recompiled - eg QKDRIVER, stuff like that.
