Expired CA certificates remain in the VECS Trusted Root store and vmdir after upgrade.
VMware vCenter Server
Product Release: 8.0U3
vCenter 8 performs certificate health checks across VECS and VMware Directory Service. Any certificate with an expiration date in the past is flagged as unhealthy. The upgrade does not automatically remove outdated CA certificates, therefore stale/expired certificates persist and generate alarms.
Use the vCert tool on the VCSA to identify and remove all expired certificates from both VECS and the VMware Directory (vmdir).
Please ensure you have a valid VAMI-based backup or offline snapshots of ALL vCenter/PSC nodes in the SSO domain before continuing.
Steps to perform
Removing expired certificates eliminates the stale entries that trigger vCenter’s certificate health alarms. After removal, certificate stores contain only valid certificates, and vCenter certificate alarms clear successfully.
