Install two certificates for the same website IIS 8
I would like to know if it's possible to install two certificates on the same IIS 8 web site i.e. to represent the same domain name?
The reason behind this is that we use IIS 8 as a reverse proxy to handle incoming AS2 traffic. The AS2 traffic will be signed with our public key, and the certificate for that is through godaddy and expires in a few weeks. When I renew the certificate, the old one will be revoked within 72 hours. This isn't long enough for us to distribute the new certificate to our AS2 customers and we can't afford to lose connectivity with them.
Godaddy have recommended that I purchase a new certificate under the same domain name, and that this can sit alongside the old one on their system. If I can install this alongside the old one, then this should solve my problem. Our AS2 customers then have a few weeks to install the new cert on their systems before the old one expires.
Any help is much appreciated.
