Hi all,
Can somoeone tell me if it is a requirement to have at least one instance of Exchange 2010 installed into what is an Exchange 2003 forest to allow for a cross forest migration to an all Exchange 2010 forest. My understanding is that it is and that the MRSProxy service is used on each to allow for proxy of new-moverequests to Exchange 2003 mailboxes.
Any advice appreciated.
Nick
