Verify Preparations Are Complete for Upgrading vCenter Server
Verify that all components of your environment are ready to upgrade vCenter Server.
Your pre-upgrade conguration of vCenter Server services impacts your post-upgrade deployment of
vCenter Server services.
n
If you have vCenter Server 5.0, you can choose to congure either an embedded or an external
Platform Services Controller instance during the upgrade. See “Upgrade vCenter Server 5.0,” on
page 83.
n
If you have vCenter Server 5.1 or 5.5, you do not have a choice of deployment options during upgrade.
See “Upgrade vCenter Server 5.1 for Windows,” on page 85 or “Upgrade vCenter Server 5.5 for
Windows,” on page 87.
n
If your vCenter Server 5.1 or 5.5 services are deployed on the same virtual machine or physical server,
the installer upgrades them to vCenter Server 6.0 with an embedded Platform Services Controller
instance.
n
If your vCenter Single Sign-On 5.1 or 5.5 service is deployed on a dierent virtual machine or physical
server than vCenter Server, the installer upgrades the deployment to vCenter Server 6.0 with an
external Platform Services Controller instance. For information on the consolidation of distributed
services during the upgrade, see “Migration of Distributed vCenter Server for Windows Services
During Upgrade to vCenter Server 6.0,” on page 75 and “vCenter Server Example Upgrade Paths,” on
page 28.
N You cannot change deployment of vCenter Server services after the upgrade.
For information about upgrading services, see About the vCenter Server 6.0 for Windows Upgrade
Process,” on page 73. For information about upgrading an externally deployed vCenter Single Sign-On
server, see “Upgrade vCenter Single Sign-On 5.5 for External Deployment,” on page 81.
For information on synchronizing clocks, see “Synchronizing Clocks on the vSphere Network,” on page 67.
To download the installer, see “Download the vCenter Server for Windows Installer,” on page 77
Prerequisites
After you have veried basic compatibility and upgrade readiness for your database, network, local
database communication, and ESXi hosts, you are ready to perform the nal tasks to assure upgrade
readiness of your environment.
Procedure
1 Log in as a member of the Administrators group on the host machine, with a user name that does not
contain non-ASCII characters.
2 Make sure that your pre-upgrade conguration is correct for the post-upgrade deployment you want to
achieve.
n
For vCenter Server 5.1 or 5.5, to upgrade to an embedded Platform Services Controller deployment,
make sure that your vCenter Server and vCenter Single Sign-On instances are deployed on a single
virtual machine or physical host.
n
For vCenter Server 5.1 or 5.5, to upgrade to an external Platform Services Controller deployment,
make sure that your vCenter Single Sign-On is deployed on a separate virtual machine or physical
host from its associated vCenter Server.
