Installation of SSL Certificates on Exchange 2016

Installed Exchange server creates a certificate which is the self-signed certificate further includes the FQDN and server hostname. A hostname generally establishes external connections so that they can prevent an internal server from being the internet exposer.

Note: When migrating the CAS role to Exchange 2016, we need to ensure that Exchange 2016 uses the same certificates as that of Exchange 2013.  For which we need to perform a switchover to point ‘X’ records uses by the old Exchange Server to Exchange 2016.

Below are the mentioned steps to install SSL Certificates
