SSL certificate installation on add on domain

I have a Standard UCC SSL Certificate that can protect up to 5 domains. 

I currently have 2 domains protected now

                *My Exchange server with two domains below

                                - email1.abc.com

                                - email2.abc.com

I need to add 2 more domains to be protected. One new domain will reside on the same Exchange server above and another one on a different RDS server:

                - email3.abc.com

                - rds.abc.com

 

After modification, my Standard UCC SSL Certificate will look like the following:

                - email1.abc.com

                - email2.abc.com

                - email3.abc.com

                - rds.abc.com

 

email1, email2, and email3 will be on Exchange server.

rds.abc.com will be on RDS server

 

I know I need to reissue/regenerate a new certificate and reimport to my Exchange server, but how do I generate a new certificate for the RDS server?  If I generate a new certificate for the RDS server, will my certificate for my Exchange server be intact?

 

Any suggestion or comment will be greatly appreciated.

 

Thank
