Welcome to the Community,
if you have vCenter Server in place to manage the hosts, you can simply migrate the VM's from the GUI. With stand-alone hosts it's not that easy. However there are options too like using VMware Converter (make sure you disable the post conversion tasks), Exporting/Importing as OVF (may require some network reconfiguration), or - if the VM's virtual disks are thick provisioned - copy the VM's files using e.g. WinSCP or FastSCP.
