Can I convert a virtual machine from 5.1 to 6.5?

Hi folks,

I have an issue using Converter Stand Alone:

I try to do a V2V from a vm in ESXi 5.1 to ESXi 6.5. Both ESXi´s in different vCenters. I´m using Converter Standalone 6.2.0

Following the compatibility Matrix it seems it´s impossible.

I appreciate any help in how to convert this machine.

Thanks.
