It’s a good idea to create a backup of the certificate before you remove it as a precaution.
Note that we don’t recommend removing the original system-generated self-signed certificate.
This can cause you server to become unstable (especially with Windows servers).
So, technically, when you ‘renew’ a certificate you are purchasing an entirely new certificate, just for the same company/domain.
Because of this, Digi Cert must issue a new SSL Certificate to replace the existing one on your server and you must install the certificate just like you did before.
Because it can be difficult to remember all the company and domain information for your expiring certificate, Digi Cert automatically includes some of this information in our renewal request wizard.
If you need to update this information you can do so during the request process.
Renewing Digi Cert SSL Certificates is easy; just follow the basic instructions below to renew your certificate.
Note that for some server types these steps may vary. In the My Orders tab, click the Renew button next to the certificate you want to renew and complete the renewal request.
After you complete the renewal request, Digi Cert will perform a quick cross-check verification.
If your organization’s information was changed in the CSR, you may need to provide new documentation to verify the changes.
On your server, install and configure the new certificate.
We recommend that you make sure the new certificate is installed and configured properly before you uninstall your old certificate.
This way if there is a problem with your new certificate or if there is a delay in getting your new certificate installed your sites are still secure.
