I need to transform XYZ data from the currently used DHHN2016 height (EPSG:7837) to the older DHHN12 height (EPSG:7699). Unfortunately, the various transforming options don't seem to be able to do this. E. g. EsriReprojector, with "Use Vertical Transformation" checked, only lists <None> as option under "Vertical Transformation".
To complicate things further, the switch to DHHN2016 did not happen directly from DHHN12, but first to DHHN92. So the transformation might need to be done with an extra step: DHHN2016 height (EPSG:7837) -> DHHN92 height (EPSG:5783) -> DHHN12 height (EPSG:7699). However there is no option for this way either.
Perhaps a combination is necessary? In this case it would be 25832+7837 to 31468+7699 (or 25832+7837 -> 31468+5783 -> 31468+7699).
I added the Reproject files to the install directory but that had no effect. I also don't have "PROJReprojector" available for some reason(?).
