Renew CA certificate with the same key as older of two CA certificates

Renew CA certificate with the same key as older of two CA certificates

I have a CA installed on Windows Server 2022. It has two certificates:

  • one older that is about to expire on 30.07.2026

  • second newer, to expire on 08.03.2030

I have many certificates created using the first key used on other devices.

The newer certificate was created with a new key, so certificates issued with the second CA certificate with the new key do not authorize users on device with first CA cell installed.

So I want to create a new certificate that has the same key as the old CA certificate, but will have extend the period of its usability.

How to do that on Windows Server 2022?

Comment: Did you read the documentation at learn.microsoft.com/en-us/windows-server/identity/ad-cs/… or find the command line utility certutil -renewCert ReuseKeys ? How did these not solve your problem?
