Need to remove domains from SSL SAN so can i renew the existing SSL certificate?

I had to remove two domains from the SAN list in our GoDaddy SSL certificate for our mail domain.  The question I have since I received the new verified certificate is can I create a CSR from a renewal request on the Exchange server even though it will be missing those two domains? Or do I have to create a completely new certificate request?  If so, what is the best way via PowerShell to get all the information to fill the new certificate?

You need to redo it again,  Expedite a new CRS certificate from your exchange, add whatever domain such as

1- mail.mydomain.com
2- autodiscover.mydomain.com

Then, apply that cert to any exchange you have in your environment.
