Nutanix Move (Move) is a cross-hypervisor mobility solution to move VMs with minimal downtime. Move supports migration from the following sources to targets, where first platform being the source and second platform being the target.

Starting with version 3.0 Move supports Hyper-V which means that you can now migrate consolidate your workloads from ESXi, AWS EC2 and Hyper-V on Nutanix and perform reverse migration in some cases.

For a list of supported OS versions, Hyper-V versions, port requirements, useful commands and caveats be sure to check KB-6667 Hyper-V: Move | Basic understanding and troubleshooting.
