Exchange Server 2016 Update SSL Certificate after Adding SAN.

I bought UCC SSL certificate from GoDaddy last week and installed it successfully on the Exchange Server 2016 MailBox. I added more SAN to the certificate and downloaded it to the server. The problem is, I can't find where to update the existing certificate on the Mailbox Server ECP or Edge Transport server.

1) Update Existing SSL Certificate on Exchange Server 2016 Mailbox Role.
2) Import the certificate into Edge Transport Server.

The Microsoft Exchange Server is on premises. Not a hosted service.

The ideal person will be willing to use Skype Screen Sharing to give me instruction.
