Hi There,
I am planning to introduce New exchange 2013 Enviroment CAS and MBX servers ,in my existing 2010 server, right now i have CAS array which has 3 CAS server (Exch 2010) now my plan is to install a 2013 CAS servers and build a new CAS array and add both the new 2013 CAS servers to the new CAS array and then start moving mailbox from 2010 to 2013 servers.
So my question is can i have 2 CAS Array in same AD site without effecting my mailbox migration process anytime and also if migrated mailbox on 2013 has access to Mailbox on 2010 (auto mapped in outlook) will have any issues??
