VMware
Platform Services
Controller Changed
from vCenter Server 5.5
The VMware Platform Services Controller contains common infrastructure
services such as vCenter Single Sign-On, VMware certificate authority,
licensing, and server reservation and registration services.
You can deploy a Platform Services Controller instance on the same virtual
machine (VM) or physical server as vCenter Server, which is
vCenter Server with an embedded Platform Services Controller instance.
You can also deploy a Platform Services Controller instance on a separate
machine or physical server, which is vCenter Server with an external
Platform Services Controller instance.
vCenter Server
Component Services
Deployment Changed
from vCenter Server 5.5
vCenter Server component services are deployed in either the
vCenter Server or Platform Services Controller group of services. vSphere
common services can no longer be upgraded individually.
vCenter Server 5.5 services that are deployed individually before the
upgrade are migrated to the appropriate service group during the upgrade
process. The upgrade software migrates, upgrades, and configures existing
vCenter Server 5.5 services as needed.
n
vCenter Single Sign-On credentials, certificates, and ports are migrated
to the Platform Services Controller instance.

Tagging data and licensing is migrated to the
Platform Services Controller instance.

see Distributed vCenter Server 5.5 for Windows Services Relocation
During Upgrade or Migration.
