New GDA2020 Geocoordinate Systems in CE - how does it work?

Hi,

Can someone explain how the newly added Projected Australian GDA2020 GCS works in Microstation CE U11?

We have the old GDA94 GCS group, a new GDA94-7P (7 Parameter Transformation to 2020), GDA94/GSB (GDA94 to 2020 using Grid Shift files) and a plain GDA2020 GCS group. If I reproject the data from the old GDA94 to the GDA-7P or GDA95/GSB GCS settings my data moves as expected, however nothing happens if I go from the old GDA94 to the new GDA2020.

How is this supposed to work?

Regards,

Mark
