I'm about to renew my cert for exchange and after that, I will migrate to 2013.
Here is what I have now:
- my external domain: domain.com
- my internal domain: local.domain.com
My cert is for:
Because my internal and external domain is different, I'm using the DNS zone trick so my email server is accessible using the same name internally and externally.

My current setup is only one server but my 2013 setup will incorporate 2 servers: I will be using DAG for database availability and DNS round robin for CAS.
MY QUESTION IS:
what do I need on my new certificate ?
First of all, I know it will be 'legacy' name for 2007 server but should it be legacy.local.domain.com or legacy.domain.com ?
Also, since I will have 2 new servers using DNS round robin, they will be both using mail.domain.com name in CERT, am I right ?
