Install or Upgrade vCenter Single Sign-On in a Basic Deployment
Create or upgrade vCenter Single Sign-On in a vCenter Single Sign-On installation.
These instructions let you install or upgrade vCenter Single Sign-On only. You must install or upgrade
vCenter Single Sign-On and upgrade Inventory Service before upgrading vCenter Server. For most
deployments, you can install vCenter Single Sign-On, the vSphere Web Client, vCenter Inventory Service,
and vCenter Server together on a single host machine by using vCenter Server Simple Install. See “vCenter
Single Sign-On Deployment Modes,” on page 33 and “Use Simple Install to Upgrade vCenter Server and
Required Components,” on page 65.
For more information about vCenter Single Sign-On, see “How vCenter Single Sign-On Affects vCenter
Server Upgrades,” on page 32 and the vSphere Security documentation.
NOTE vCenter Server 5.5 supports connection between vCenter Server and vCenter Server components by
IP address only if the IP address is IPv4-compliant. To connect to a vCenter Server system in an IPv6
environment, you must use the fully qualified domain name (FQDN) or host name of the vCenter Server.
The best practice is to use the FQDN, which works in all cases, instead of the IP address, which can change if
assigned by DHCP.
