Hi Folks,
this is going to be my first cross forest migration, I am quite curious about it. Let put the scenario in front on you, please let me know what could be the best possibility to achieve it.
we have 2 forest in our organization, A.Com a user forest and B.Com a resource forest containing exchange 2010. there is 2 way trust between the 2 forest and the users in forest A.com use the exchange in Forest B.com...
we create users manually in User forest(A.com), and FIM is installed and that is responsible for creating the users in the resource forest (B.Com). those mailboxes are the linked mailboxes.
we are going to have a cross forest migration by creating the new forest C.com, where all the users will be migrated from forest A.com, but we will keep using the forest B.com as resource forest for the users in C.com forest. how these mailboxes will be linked again with those migrated users in C.com, whose mailboxes are already in the resource forest (B.com).
please guide me about above scenario.
BR, Phaixan
