Renewing an SSL certificate is equivalent to applying for a new one in the console, and you need to install and deploy it on the server. The new certificate does not affect the usage of the existing one.
If you need to modify the certificate information, please apply for a new one.
Renewing the existing certificate holds the following advantages over purchasing a new one:
Instead of entering application information again, you only need to confirm the original certificate's application data pulled automatically by the system and proceed with the payment. After making the payment, please upload the confirmation letter and wait for certificate review.
After renewal, the remaining available time of the original certificate and an extra 1 to 90 days will roll to the validity time of the new certificate for free. You will not experience any loss in certificate validity period due to renewal.
For a paid DV certificate, the fast renewal option will become available 3 months before its expiration date. You can open the fast renewal window by clicking Fast Renewal in the "Status" column of the certificate in the certificate list in the SSL Certificate Service Console.
In the SSL certificate renewal prompt window that pops up, confirm the information and click Renew Now to enter the renewal page.
