However, when i take the same pogram file, open with logo 8.4 and transfer to a new logo 8.4 it seems like the VM parameter mapping is not working / imported correctly. Node red nodes just keeps flashing online/offline. Anybody have an idea what is wrong ?

I guessing that your Node-Red implementation use Snap7. LOGO 8.4 is a new hardware with different configuration. It could be as simple that you couldn't use LOGO 8.4 hardware with the implementation in Node-Red. Thats why you have the option to select hardware in LSC. This way you could pick a hardware that Node-Red do support. I do know that Snap7 use 2 different LOGO hardware and that is the thinking I get when I read your issue. If we invent new hardware we also get new bootloader. I believe that is the case when we select hardware in LSC we get older bootloader when when we download the project to the hardware. I only guessing here.
