You can use Custom Install to upgrade vCenter Single Sign-On, vCenter Inventory Service, and vCenter Server separately to customize the location and configuration of the components.
About this task
These instructions upgrade vCenter Inventory Service only. You must install or upgrade vCenter Single Sign-On before upgrading Inventory Service and vCenter Server.
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.
Download the vCenter Server Installer.
