How to upgrade vCenter Server Appliance 5.5 to version 6.0
The latest version of VMware vSphere ships with a new version of the vCenter Server Appliance (vCSA). Let’s have a quick look on how to upgrade the vCenter Server Appliance 5.5 to version 6.0.
As always, before you begin, make sure you read the vSphere 6 upgrade guide (chapter 5: Upgrading and patching the vCenter Server Appliance). Also, before you can proceed with the upgrade, you must install the VMware Client integration plug-in from the ISO located in the vcsa folder.
This article describes the upgrade process of the vCenter Server with an embedded Platform Services Controller. If you want to use the vCenter Server Appliance with an external Platform Services Controller, you must deploy a new vCenter Server Appliance. For more info on how to deploy the vCenter Server Appliance, see vSphere 6 Installation and Setup guide.
