Client has a root domain and several child domains. Exchange 2007 servers are installed in the root domain. The server roles are distributed - MB, HT and CAS. Some child domains have a single Exchange 2007 server with combined roles and some child domains have a single Exchange 2010 server with combined roles. All Exchange servers in all domains are part of the same Exchange Organization. A migration of mailboxes on root domain MB servers only to Office 365 is planned. A hybrid server Exchange 2013 server will be deployed in the root domain to support the migration. To support this, which child domains should setup.exe /preparedomain:<fqdn> be run against?
Thanks in advance.
