We have 2 domains, Domain1=NT4 and Domain2=W2K. Exchange 5.5 was installed on Domain1 and serves both domains. We now plan to disolve both domains 1 and 2 and create Domain3 (W2K) across the WAN. Since the Exchange organization was created under Domain1 with the service account in Domain1, how do we migrate the various sites between domains/organisations?
