You can use the GUI installer to perform an interactive upgrade of a vCenter Server Appliance 5.5 or 6.0 that uses an embedded vCenter Single Sign-On or Platform Services Controller to vCenter Server Appliance 6.5 with an embedded Platform Services Controller. You must run the GUI upgrade from a Windows, Linux, or Mac machine that is in the same network as the appliance that you want to upgrade.

You can deploy version 6.5 of the vCenter Server Appliance and Platform Services Controller appliance on hosts that are running ESXi 5.5 or later and on vCenter Server instances 5.5 or later.

Upgrade Workflow of a vCenter Server Appliance with an Embedded Platform Services Controller
Upgrade workflow that consists of two stages

1

With stage 1 of the upgrade process, you deploy the OVA file, which is included in the vCenter Server Appliance installer, for the new vCenter Server Appliance with an embedded Platform Services Controller.

2

When the OVA deployment finishes, you are redirected to stage 2 of the upgrade process to transfer the data from the old appliance and start the services of the newly deployed vCenter Server Appliance 6.5 with an embedded Platform Services Controller.
