Make VMCA an Intermediate CA
You can replace the VMCA root certicate with a certicate that is signed by an enterprise CA or third-party
CA. VMCA signs the custom root certicate each time it provisions certicates, making VMCA an
intermediate CA.
N If you perform a fresh install that includes an external Platform Services Controller, install the
Platform Services Controller rst and replace the VMCA root certicate. Next, install other services or add
ESXi hosts to your environment. If you perform a fresh install with an embedded
Platform Services Controller, replace the VMCA root certicate before you add ESXi hosts. If you do, all
certicates are signed by the whole chain, and you do not have to generate new certicates.

Do Not Use VMCA, Provision with Custom Certificates
You can replace the existing VMCA-signed certicates with custom certicates. If you use that approach,
you are responsible for all certicate provisioning and monitoring.
