Use the Reset All Certificates option if you want to replace all existing vCenter certificates with certificates that are signed by VMCA.
- On a Platform Services Controller node, vSphere Certificate Manager can regenerate the root certificate and replace the machine SSL certificate and the machine solution user certificate.
- On a management node, vSphere Certificate Manager can replace the machine SSL certificate and all solution user certificates.
- In an embedded deployment, vSphere Certificate Manager can replace all certificates.
Which certificates are replaced depends on which options you select.
