OVF packages uses features that are not supported

In Esx 6.0 I'm trying to import vm in .ova format but I got this message:

The OVF packages uses features that are not supported:

The OVF package requires unsupported hardware.

details: line xx: unsupported hardware family 'virtualbox-2.2'

In XML file I can see error in one of these lines, and I suppose problem occurs because vm is exported by Virtual Box.

Here is a part of xml file:

      <System>

        <vssd:ElementName>Virtual Hardware Family</vssd:ElementName>

        <vssd:InstanceID>0</vssd:InstanceID>

        <vssd:VirtualSystemIdentifier>SmartApp 16.04 php 5.6</vssd:VirtualSystemIdentifier>

        <vssd:VirtualSystemType>virtualbox-2.2</vssd:VirtualSystemType>

      </System>

Does it exist way to convert OVA hardware from virtual box to ESXi hardware 11 ? By OVFtool?
