I know that it is possible to migrate from many exchange servers to one (consolidation)
Does anyone know if it can be done the other way? From one exchange server to many?
Thanks in advance.
Yes it's possible, but not usually one of the use cases we hear of.
You can actually do m:n - say you have a consolidation of 10 source Domains, and want to move them over into two target Domains (e.g. one for financial and one for the rest of the users).
It doesn't happen very often, but it happens.
