VMware Converter is a free tool by VMware that allows the conversion of physical Linux and Windows hosts and third-party virtual machines into VMware virtual machines.

With this software you can perform P2V (Physical-to-Virtual) and V2V (Virtual-to-Virtual) migrations in an easy and intuitive way, as it can be installed on a Windows client and insert the IP addresses of the source host and the destination host (in case of a P2V migration). Converter then performs the migration by installing a dedicated agent tool on the source machine. During the migration procedure it's even possible to tweak the main parameters of the destination VM.

With its latest 6.1 release, Converter also supports Windows 10 and Hyper-V v3 virtual machines.
