I was able to successfully re-issue my existing SSL Certificate for the higher encryption (SHA2). I did not need to perform a new CSR, etc. I just did a reissue. Now, I cannot figure out how to install it in Exchange (IIS) because all of the certificate operations there seem to be based around the whole CSR process. (also, I am competent enough to use the Certificates snap-in for Windows Server if that's what's needed)
Nothing changed on this certificate, other than Sha1 to Sha2. I just want to delete the old one and import the new one... but how? All of the articles everywhere are about replacing an expired cert. I can do that in my sleep. This is different.
Thank you for posting. If this is a certificate issued by us, you would need to re-key the certificate to change the encryption type and this requires that you generate a new CSR. If you didn't generate a new CSR when you rekeyed the certificate, I'd recommend you rekey again with a newly generated CSR. If you're still having trouble after that, reach out to our support team.
Is a certificate renewed after your generate a new CSR? Please help we are also upgrading our certificate from SHA1 to SHA2
And I want to know if upgrading process includes renewed expiration date of the SSL Certificate.
