If VMCA assigns certificates to your ESXi hosts (6.0 and later), you can renew those certificates from the vSphere Web Client. You can also refresh all certificates from the TRUSTED_ROOTS store associated with vCenter Server.
You can renew your certificates when they are about to expire, or if you want to provision the host with a new certificate for other reasons. If the certificate is already expired, you must disconnect the host and reconnect it.
By default, vCenter Server renews the certificates of a host with status Expired, Expiring immediately, or Expiring each time the host is added to the inventory, or reconnected.
- Browse to the host in the vSphere Web Client inventory.
- Select Configure.
- Under System, click Certificate.
