ok, may be some process are not susceptible to restart,but how about
sending the state in the heartbeats and all the things the process
need  to start in the last point it left it`s work. For other
insignificant process like an application designed to run in parallel in
user space, it may be possible.

I Know there are a lot of complications that make this problem difficult
to solve, I agree that starting (or restarting) the process is not a
process migration. But may  be with a congruent system, with the same
hour, CPIDS etc ... make it in that way could be possible for a class of
process.

doing in that way is probably a bad idea. żin what way can you solve
that problem in a cluster environment?
