ISSUE
Attempting to replicate a hardware version 8 VM originating on a VMware ESX 5 host to a host that does not support hardware version 8 (e.g. ESX4) will result in the error:
CreateVM_Task returned an error : A specified parameter was not correct.
This is due to hardware version 8 VMs not being backward compatible with previous versions of ESX. These VMs should be replicated to an ESX 5 host instead
