I have configured a new Exchange 2013 server and it has gone quite well. I am though a little confused on the legacy setup and the certificate process for coexistence.
I have one 2007 Exchange and one 2013
I have created a DNS A record internally and externally for legacy.domain.com. This points to the 2007 Exchange server.
When I browse https://legacy.domain.com I am welcomed by a certificate error screen. Upon pressing continue it forwards to me https://mail.domain.com (which is the OWA front end for my 2007 exchange) which has no cert errors and has the third party cert (GoDaddy)
I guess my questions are...
1) Do I have to now create a new certificate with godaddy for legacy.domain.com and bind it to the 2007 exchange server?
2) How do I enable the 2007 OWA so it uses legacy.domain.com URL as its OWA address
3) Once the legacy url and cert is working on the 2007 exchange I will then point mail.domain.com to the 2013 exchange. I will also have to re-issue the original cert as mail.domain.com is hosted on a new server?
