Important:

You cannot change your deployment type during upgrade.

You cannot uninstall or reinstall individual services during the upgrade process. For example, vSphere Auto Deploy can no longer be deployed separately as it was in vCenter Server 5.5. It is part of the vCenter Server group of services for vCenter Server 6.5. For details on upgrading from 5.5 with distributed services, see Distributed vCenter Server 5.5 for Windows Services Relocation During Upgrade or Migration.

Note:

Starting with vSphere 6.5, the vCenter Server services are not standalone services under Windows SCM, instead they run as child processes of the VMware Service Lifecycle Manager service.
