First which version of Exchange are you using..?

You can renew your CA root certificate with your domain.com

In Exch 2007 & 10 New-exchangecertificate command will do that.
Renew-exchangecertificate -thumbprint -services command will renew the certificate.

Also you can perform the same through Inetmgr-- servercertificates and select the certificate and u can see renew option on top right.

The certificates have Different uses, functions.
Using the CA admin tool, renew the CA certificate.
It's up to you whether you are using the same private key or a new one.
