A lot of this depends on your actual end goal. If you want to just move the VE appliance, export a UCS (system archive), deploy a clean VE on the new hypervisor (make sure your MAC addresses don't change, you will likely need to manually change them) and restore your UCS.
If you are looking to add another VE, you will need to have a new VE license and things get more complicated.
If you just need the ASM policies and not the LTM objects they can be exported as XML and imported on the new system. If you can provide more information on what exactly you would like to do, I can provide more guidance on how to do it.
