I am in the process of planning an Server 2008/Exchange 2007 Migration.
At the moment we have 1 Exchange 2003 server with a1 domian 1 forest structure. Our blackberry server is in this forest.
I will create a new forest with a Exchange 2007 server and 1 domain. There will be a trust between my current forest and new forest.
I will then start migrating users mailboxes from the Exchange 2003 server to the Exchange 2007 server.
My question is will my BES server in the current forest be able to manage and support the migrated mailbox in the new forest? Will it be able to control mailboxes in both environments at the same time until the migration is complete?
