In particular, are you thinking about Erlang-style code swapping of processes?

OCaml's runtime is pretty much the opposite model to Erlang's in this regard, 
as it performs native compilation of code and discards a lot of type 
information.  The best way to perform hotswapping of MirageOS unikernels is to 
do it at the application level (e.g. a load balancer) rather than at the 
virtual machine level.
