I have planned to migrate exchange 2010 to 2013 with co-existance
My Existing environment exchange 2010
3 servers DC (Primary site-2 DC’s and DR site-1DC)
3 servers mailbox(Primary site-2 mailboxes and DR site- 1 mailbox)
3 servers Cas & Hub(Primary site-2 servers DR site- 1 server)
For planned to build existing AD with new exchange 2013 environment
1 server (Cas & Mailbox) –Primary site
1 server (Cas & Mailbox) –DR site
My question is after installed and configured exchange 2013 server, user’s may connect through exchange 2013 servers virtual directory which is migrated 2010 to 2013 mailboxes users only not all users from internal/external.
Rest of the users that is existing in exchange 2010 environment users, they need to connect directly exchange 2010 CAS server’s(virtual directory) not via exchange 2013 CAS(virtual directory).
Is it possible way ?
Can anyone answer my question?
