Hi,
I am working on the planning to achieve the cross forest migration for exchange 2010 with an upgrade to 2013.
in my environment Exchange 2010 is deployed in Resource forest and all the mailboxes are linked with their users in user forest.
now problem is how to get this migration done and how these linked mailboxes will be connected to their users in user forest after migration.
need food for thought...
Regards, Owais
