We have stood up a side-by-side 2013 environment. We are changing from usmail.domain.com to mail.domain.com for our 2013 environment. The cert going on our 2013 environment will have autodiscover.domain.com and mail.domain.com on it only. From a user experience standpoint, when Outlook tries mail.domain.com for a user whose mailbox resides on our usmail.domain.com system and then connects there, currently they hit a 2013 CAS which tries to proxy their connection to the 2010 environment. They get a cert error since the old FQDN is not on the new cert used on the 2013 CAS servers.
We want to know if an admin can force all 2013 CAS servers to redirect (rather than proxy) either to the given assigned 2010 CAS value or to a hard value that we manually enter. This is so we don't need to include usmail.domain.com on our new certificate.
Is this something I can control (i.e. set via shell?)
