Legacy namespace - Migrating from Exchange 2007 to Exchange 2010

Hey Experts,

I have a quick question about setting up a legacy namespace to support Exchange 2007/2010 coexistence. We basically plan to stand up 2010 SP3 alongside our 2007 SP3 organization and slowly migrate our users over to the new 2010 mailboxes. It looks we will need to go the legacy namespace route since CAS 2010 doesn't support rendering OWA for mailboxes sitting on 2007 mailbox servers, as I understand it.

My confusion deals with the certificate. Right now we have a SAN that we use with all of our exchange related hostnames. Do we have  to add legacy.mail.your-domain.com to the SAN since we have two 2007 CAS servers that are publicly facing? Is it as simple as that? We were hoping to have everything coexist without having to mess with certs on our 2007 boxes. Can someone break this down for me?

That is pretty much all you do.

Therefore on the certificate you will have:

owa.example.com (current namespace)
Autodiscover.example.com
legacy.example.com

The idea being to allow Exchange to sort out what is proxy to 2007 and what is redirected.

Certificates on Exchange 2007 aren't a huge problem. Add the name, install the certificate. As long as the old and new name resolve, you will be fine.

Don't forget to change the URLs on the servers to take in to account the new name.

Simon.
