You're playing with fire here. I expect they are not going to be compatible.

You're outside the envelope. It might work. It might cause a singularity that sucks the
universe beyond the event horizon and into a black hole. ;) Good luck with that.
You're going to be really mad if it gets to the end and either crashes or makes garbage
data, and you'll wonder why you didn't spend that time adapting to the latest code that
could have done the job properly and more rapidly using multiple CPUs and stuff.
