A renewal is basically the same as buying a brand new certificate, “renewal” is simply an industry term that is used by all providers. So, you can go through the exact same purchasing process to renew your certificate. However, if you have access to a “renewal” option when purchasing your SSL certificate, be sure and use that so you get the remaining time rolled over from your expiring certificate to your new renewal certificate.
