Hello,
We currently have 2 Exchange 2010 SP3 servers in 1 DAG. Both servers host CAS, Mailbox and Hub Role.
I want to introduce a 3<sup>rd</sup> Exchange 2013 Server and slowly move users onto a new DAG I build in Exchange 2013.
Can I create a 3<sup>rd</sup> Exchange 2013 Server with CAS and Mailbox Server Role and make the 3<sup>rd</sup> Exchange server (2013) a member of the existing (2010) CAS array then slowly perform local move requests for users mailboxes from my Exchange 2010 DAG to the Exchange 2013 DAG without any disruption to my outlook, OWA and AS clients?
