To upgrade to the latest version of the vCenter Server Appliance, you must use the Client Integration Plug-In. All of the installation files necessary for the vCenter Server Appliance upgrade are included in an ISO file which you can download from the VMware Web site.

Before you upgrade the vCenter Server Appliance, download the ISO file and mount it to the Windows host machine from which you want to perform the upgrade. Install the Client Integration Plug-In, and then start the upgrade wizard.

For information about the vCenter Server Appliance upgrade requirements, see vCenter Server Appliance Requirements.

For information about the inputs that are required during the upgrade of the vCenter Server Appliance, see Required Information for Upgrading the vCenter Server Appliance.

The upgrade of the vCenter Server Appliance is a migration of the old version to the latest version, which results in deploying a new vCenter Server Appliance 6.0 on an ESXi host 5.0 or later. The configuration settings of the vCenter Server Appliance that you are upgrading are migrated and applied to the newly deployed vCenter Server Appliance. The new appliance is assigned a temporary IP address to facilitate the upgrade from the old appliance. The IP address and host name of the vCenter Server Appliance that you are upgrading are applied to the vCenter Server Appliance 6.0 as part of the upgrade process. At the end of the upgrade, the vCenter Server Appliance that you upgraded is powered off.

Important

If the vCenter Server Appliance that you are upgrading is configured in a mixed IPv4 and IPv6 environment, only the IPv4 settings are preserved.

If the vCenter Server Appliance that you are upgrading uses a non-ephemeral distributed virtual port group, the port group is not preserved. After the upgrade, you can manually connect the new appliance to the original non-ephemeral distributed virtual port group of the old appliance.

In a DHCP environment, the vCenter Server Appliance upgrade fails if the vCenter Server Appliance you are attempting to upgrade and the vCenter Server Appliance 6.0 run on hosts that are in different networks.
