IIS Benefits
With IIS 6.0 or later, users have the ability to set up multiple sites on the same server involving the same IP address and port. If you are using this set up, we advise you to secure your website(s) with either a Unified Communication Certificate (UCC) or Wildcard Certificate, depending on your domain name(s).
Also, if users need the same SSL certificate installed on multiple IIS web servers, IIS provides them with the ability to export the configured SSL certificate from one server list and import the SSL certificate into another IIS web server; while both certificate run simultaneously.
