6.0.2

Table Of Contents
If you have a simple installation with all vCenter Server 5.1 or 5.5 components on the same system, the
vCenter Server 6.0 software upgrades your system to vCenter Server with an embedded
Platform Services Controller instance. The software upgrades your vCenter Server common services such as
vCenter Single Single-On in the Platform Services Controller instance. The rest of the vCenter Server
components, such as vSphere Web Client Inventory Service, are upgraded to 6.0 as part of the
vCenter Server group of services. The software upgrades vCenter Server and all its services in the correct
order to the same version.

an external Platform Services Controller instance.

If your conguration includes a vSphere Auto Deploy server, the upgrade process upgrades it when
upgrading the associated vCenter Server instance. You cannot use a vSphere Auto Deploy server that was
included with an earlier version of the product in conjunction with vCenter Server 6.0. If your vSphere Auto
Deploy server is running on a remote system, it is upgraded and migrated to the same system as
vCenter Server during the upgrade process.
