Validity Periods and Replacement of the Current and New SSL Certificates

Validity Periods of Current and New SSL Certificates

After the certificate is renewed, the current certificate is still valid. The validity period and usage of the new certificate depend on whether certificate details have changed:

• Certificate details not changed

  If the certificate details remain unchanged, the actual validity period of the new certificate equals to the remaining validity period of the original one plus the requested validity period of the new one. A maximum of 30 days can be added to the validity period of the new certificate. If you have not enabled auto-renewal, you are advised to apply for a certificate 30 days before the expiration.

  For example, assume that your current certificate expires on October 1, 2019, and you request a new one-year SSL certificate with the same details from the same CA on August 31, 2019. If the new certificate is issued on Sept. 1, 2019, it will be valid from Sept. 1, 2019 to Sept. 30, 2020.

  This rule is formulated, interpreted, and clarified by the CAs. If you have any questions, we will work with you to communicate and negotiate with the CAs.

  In this case, the two certificates are considered as the same certificate and in use concurrently.

• Information about the new certificate is modified during manual renewal. For example, the domain name, certificate type, or company name is different from that of the old certificate.

  The validity periods of the current and new certificates are calculated separately.

  The use of the new certificate does not affect the current certificate. The current certificate can continue to be used until it expires.

Does the Replacement of Old Certificates with New Ones Affect Services?

To replace the certificate that is about to expire or update the certificate in the corresponding cloud product, manually install the new certificate on your server. A certificate application must be submitted to the CA when you purchase a new certificate or renew a certificate.

You can replace the old certificate with the new one once it is issued. The replacement does not affect services.
