When a certificate is near its expiration date, the certmonger daemon automatically issues a renewal command using the certificate authority (CA) helper, obtains a renewed certificate and replaces the previous certificate with the new one.
You can also manually renew a certificate in advance by using the getcert resubmit command. This way, you can update the information the certificate contains, for example, by adding a Subject Alternative Name (SAN).
Follow this procedure to renew a certificate manually.
