5. Upgrading hosts with Update Manager and vCenter Server 5.5
6. Upgrading virtual machines
If all the components of the existing vCenter Server infrastrucure are installed on the same machine, the easiest and fastest upgrade way it to select Simple Install on VMware vCenter 5.5 Installer screen. Remember that upgrading from 5.0 or 5.1 is much easier as SSO will be already installed and the upgrade of SSO will be almost seamless.
It will upgrade all necessary components of vCenter Server, starting with SSO. As you can see, I am upgrading from a version with SSO already installed (i.e. 5.1) so it says it will upgrade it.
After a few checks the upgrade process for SSO will start making usre that SSO users, groups and Lookup Services artifacts are migrated. The previous version will be uninstalled and the new one configured:
After asking if the vCenter Server database should be upgraded
the installer will ask you a few other questions like if host agents should be updated automatically once vCenter Server upgrade is done or which account vCenter Server service should run on as well as you will be able to customized port used by vCenter Server. Finally the upgrade starts:
