Hello
We use IIS as a reverse proxy for an internal EDI (AS2) server. I therefore have an SSL certificate installed, issued by godaddy, and all our AS2 partners have the public key.
I need to renew the certificate and reduce any potential downtime in communications.
From my research I believe it is possible to renew the certificate using the original CSR, therefore keeping the original key pair, so that our partners can still use the 'old' certificate with the renewed one we will install on our IIS server. We then have a few weeks to send out the new certificate to our partners before the old one expires.
Can anyone confirm the above is correct please?
I don't think the original CSR was created on this particular IIS server (it's a wildcard certificate, so we use it on several servers) - would that cause any issue?
Also, how would I go about installing the renewed cert on IIS 8? Is it best to use 'complete certificate request' or to remove the old one and import the new one?
Many thanks,
James
