Hi All,

          As it is required to move Public Certificates from SHA1 hash algorithm to SHA2, is it also necessary to upgrade certificates within the Internal PKI infrastructure? Apart from that since Chrome and Microsoft's browser will not trust SHA1 certificates...does it has any impact on Server to Server communication as well? for example EAP-TLS, RADIUS, Lync or Exchange, RDP and so on....

       I will also appreciate for some material which will guide me best practice to upgrade to SHA2 and is it really necessary for server to server and server to client communic
