Exchange 2010 Certificate

So I am upgrading from Exchange 2003 to 2010. I'm plugging away and have just received my new certificate from GoDaddy with the multiple domains that I understand Exchange 2010 needs:
domain.com
mail.domain.com
autodiscover.domain.com
legacy.domain.com

Here is my question. When I look at the old SSL Cert on my Exchange 2003 and look at the subject line under the details tab it says:

CN=mail.domain.com
OU=Domain Control Validated
O=mail.domain.com

However, when I look at the new cert on my exchange 2010 server and look in the same spot it says:
CN=domain.com
OU=Domain Control Validated
O=domain.com

The Subject Alternative Names seem correct. My concern is that OWA will not work. Is everything set up properly? Does the CN and O names under subject make a difference?

Thanks

what you can see in the 'issued to' part.
If there is mail.domain.com then no problem. Otherwise you recreate csr.
you will get the correct command from digicert's website.  
just google for 'digicert csr creation tool'

CN should be common name i.e.mail.externaldomainname.com

I recommend you reissue the certificate.

Generate the comamd from belwo site.

If your exchange is 2010 you can see the link to csr creation in exchange2010
