# Register a renewed certificate

Available in Classic and VPC

You can update a registered external certificate with a new certificate. The certificate retains its original number and name. If it is integrated with Load Balancer, renewing it in Certificate Manager automatically replaces the certificate used by Load Balancer.

              Caution

              

Registering a renewed certificate replaces the existing certificate information with the new values. Connected resources will automatically use the new certificate, and automatic rollback to the previous certificate is not supported.

              Note

              

You cannot register a renewed certificate that is integrated with Global Edge.

## Requirements for registering a renewed certificate

The following requirements apply when registering a renewed certificate:

- You can add and remove domain names.
- You cannot remove all domain names from certificates.
- You cannot change key types and sizes.
