Hello,
We are currently migrating mailboxes from Exchange 2010 to an Exchange 2013 environment.
We are using one SAN certificate for both Exchange 2010 and Exchange 2013 CAS with internal/external DNS names.
Our SAN certificate is about to expire. It's not possible anymore to place internal DNS names in our SAN certificate.
What are my options for the Exchange Server 2010 environment? So that the reverse proxy from Exchange 2013 to Exchange 2010 for Outlook Anywhere continues to work.
Can I expect other problems with the coexistence environment after the certificate expires?
DNS Names SAN:
DNS Name=webmail.******.com
DNS Name=exvip.domain1.local
DNS Name=EX2010-CAS01.domain1.local
DNS Name=EX2010-CAS02.domain1.local
Specifications:
Exchange Server 2013 (CAS, MBX, HUB - x2 - EX2013-MR01.domain1.local & EX2013-MR02.domain1.local)
Virtual directory's: webmail.******.com (internal/external - split DNS)
Exchange Server 2010 (CAS, HUB - x2 - EX2010-CAS01.domain1.local & EX2010-CAS02.domain1.local)
Exchange Server 2010 (MBX - x2)
Virtual directory's: exvip.domain1.local
Thank you in advance,
Nieck
