I have a certificate that includes 1 domain and about 8 different subdomains. I’d like to split them up so each subdomain has it’s own certificate because I’m finding it difficult to manage the certificate, and when I want to add a subdomain I have to reissue the certificate with all of the subdomains again plus the new subdomain — unless there’s a way to add just one additional domain to an existing certificate? I don’t think there is.
To split them up so each domain and subdomain has it’s own certificate, do I need to revoke the main certificate first, then re-issue the certificates for each subdomain? As a test I created a new certificate for one of the subdomains and it was successful. But the subdomain is still also listed as a domain covered under the main domain certificate, too, so I guess that means I could use either certificate for that one subdomain if I wanted?
