To change the virtual hardware or virtual machine options in a template, or to upgrade an application, you must convert the template to a virtual machine. After you have edited the virtual machine, convert it back to a template.

You must be connected to vCenter Server to edit a template. You cannot work with templates if you connect the vSphere Client directly to an ESX/ESXi host.
