Certificates are valid only for a certain period of time. To ensure that you have no service interruptions, you should request a certificate renewal from your certificate authority before the date that the certificate is set to expire. When you renew a certificate, you are replacing the expired certificate with a new certificate. The new certificate contains the same public key as the expired certificate.
The process for renewing a certificate involves the following activities.
Select the certificate that is about to expire, and generate a certificate signing request (CSR) for the certificate. See Renewing certificates – creating the CSR.
Submit the CSR to your certificate authority (CA). See Renewing certificates – submitting the CSR to certificate authority (Microsoft example).
Your certificate authority will processes the CSR and issue a new server certificate for you to download.
Download the new certificate to your AE Services administrative workstation, and save it with a unique name (for example, C:\aescert.cer).

The certificate data you import into AE Services must be PEM-encoded (Base 64). If your CA issues certificates in DER format, you must convert it to PEM format before importing it into AE Services. See Converting a DER file to PEM. |
Replace the old certificate with the new certificate. See Renewing certificates – replacing the old certificate with the new certificate.
