You can upgrade a vCenter Server for Windows instance with an embedded or external vCenter Single Sign-On to a vCenter Server Appliance instance with an embedded Platform Services Controller.

When you upgrade a vCenter Server instance with an embedded vCenter Single Sign-On on Windows, you upgrade the entire deployment at the same time.
