You can export virtual machines, virtual appliances, and vApps in Open Virtual Format (OVF) and Open Virtual Appliance (OVA) . You can then deploy the OVF or OVA template in the same environment or in a different environment.
In vSphere 6.5 and later, you cannot export OVA templates, OVF templates is the only option.
In previous versions of vSphere, you needed to install the Client Integration Plug-in to deploy and export OVF or OVA templates. vSphere 6.5 no longer requires that you install the Client Integration Plug-in to export OVF templates or to deploy OVF and OVA templates.
