A reissue is a new issuance or update of an existing certificate. Reissuing certificates may be required if the server changes and a new CSR key (private key) is needed or if the private key is lost. The reissue is free of charge. The certificate term and other date relating to the certificate are not changed during a reissue. However, it is possible to specify a new CSR or to extend the term if the certificate was ordered with a Multi-year Plan.
