HP wrote a JIT to migrate old applications to their new hardware. So did Apple, twice. I don't know if IBM were the first but they've done it a few times as well for their mainframe hardware.
In HP's case, they tried running their JIT to translate from architecture B to architecture B and ended up with better performance than running it directly.
