That might be a very naive view of things, but can't you extract a test suite of the current system (including non-regression tests) to use it to develop the new system? Or do it part by part, ship of Theseus style?

Not sure that gonna work.
Operating systems abstract away hardware differences, and providing portable APIs to userspace processes. Internally, OS kernels are spending non-trivial complexity dealing with random hardware shenanigans. Can't unit test them.
