comment Certification authority root certificate expiry and renewal
Awesome reply, thanks! So all hope is not lost, and I will only have to upload the new root cert to all clients for them to trust? That's even better than I thought, because OpenVPN allows multiple CA certificates in one file, so I can simply put both the old and new CA cert into a single file and the transition should be seamless.

Does the renewed root certificate still validate client certificates signed with the old root certificate? If not, what's the advantage of renewing over starting from scratch? It looks like the only thing the old and new root certificates have in common is the private key.

This reply seems to suggest that it is possible to renew a root certificate, by re-using its key. But I suspect this is no different from starting from scratch, as the new cert will have a different signature, and hence won't validate existing client certs.
