Before you upgrade or migrate your environment to vSphere 7.0, you must move any deprecated deployment topology to a supported deployment topology.

When you first install vCenter Server 6.5 or 6.7, your deployment includes either an embedded Platform Services Controller or an external Platform Services Controller.

The installer does not validate whether the Platform Services Controller is external or embedded with vCenter Server. Although many types of join operations are possible, not all resulting topologies are supported. Before you upgrade or migrate your environment to vSphere 7.0, you must move any deprecated deployment topology to a supported deployment topology.
