DigiCert SHA2 Secure Server CA expiring on 3/8/23

DigiCert issued this KB article regarding the expiry.

We have identified this certificate in a number of our vSphere trust stores.

Am I correct in assuming we'll need to reissue any certificates signed with this expiring certificate? Or can we simply install the G2 version of the cert?
