- Power off the VM
- Download and run WinSCP.
- Select SCP as the protocol, enter the ESXi host IP and click connect. Login as root when prompted
- Browse to /vmfs/volumes/Datastore_name
- Now you can copy the VM folder in its entirely to a disk on your local machine.
- Once done, you can copy it back to any ESXi host using the same method.
- Once copied back, you can re-import it into the inventory
