I have deployed two Exch 2013 with CAS/MBX. I have 600 Mailbox's in my current production Exchange 2010 server.
currently all my OWA , outlook , Mobility is accessing the Exch 2010 using mail.mydomain.com.
I have exported the current certificate from Exch 2010 and imported to both Exch 2013 servers. I will be moving my mailbox's 100 mailbox daily and I need them to continue access the current mail facilities ( OWA. Mobility etc ) using the same URL as mail.mydomain.com.
can someone advise what is required to have the same Certificate name or any advise
