StarWind V2V Converter is a free download tool that allows
the conversion and cloning of VMs from one format to another and is
utilized when migration or hypervisor switch is required. Compared to
typical converters built into hypervisors, StarWind V2V Converter
performs bi-directional conversion between multiple VM formats. The
software supports the most widely used formats: VMDK, VHD/VHDX (Windows
Repair Mode aware), StarWind native IMG and QCOW.
