When exporting a hosted feature service as FGDB either through the web portal interface via AGOL or REST via create a replica, the vertical component of the data set is dropped.
Currently have a hosted feature set in EPSG:2193 and with EPSG:7839 as vertical so can use scene viewer to check and correct vertical geometry in ArcGIS Pro, but doing this via the Hosted Feature is painfully slow.
When exporting as a FGDB via AGOL, the resulting FGDB only has EPSG:2193, no vertical!
When I open that in ArcGIS Pro I see the Z geometry in Attributes but cannot modify verticles as the edit tool is disabled via bad geometry.
The only way I can get the vertical CRS is with Feature Class to Feature Class via ArcGis Pro.
Exporting via AGOL is breaking the dataset.
