I have mailboxes in my current Exchange 2010 Server in old_domain.com, within its own forest, that I'd like to move to Exchange 2013 in new_domain.com in a totally new forest. I have established a trust between both forests.
Is this possible? Maybe with Powershell? Does anyone know of resources to help me do this? Do I need to migrate the mailbox enabled user accounts (I'm using ADMT 3.2 tool) before this is possible? If the mailboxes CAN'T be moved (that seems unlikely), could I backup from Exchange 2010 and restore to Exchange 2013?
Just for clarification - is what I'm trying to do an InTRAforest move or InTERforest move?
