AFAIK there are incompatible in both the ways. I found this thread: which shows that there are people using the i386 version on the AMD64. It makes sense, since there aren't dedicated amd64 versions of windows applications. I must admit, I'd forgoten it has it's own FreBSD installation ISOs, so I guess there is no smooth upgrade path from i386 to amd64. Maybe I'll do that with 5.4.
