Migrating from Grain<SomeState> to Grain<OtherState>

@sergeybykov I was just wondering if there is any procedures for migrating grains State data?

It so far feels like using State for anything other than highly simple/throw away-able data is dangerous as if it goes to production your kinda stuck to that state model otherwise the serialized can't de-serialize.

Is there a better way other than just avoid State all together and doing the work manually inside of the ActivateAsync?

Cheers,
Michael.
