I have a shapefile with something similar to EPSG Projection 31256 - MGI / Austria GK East. However, the EPSG code states a false easting value of 0, while my prj file contains 750000 (that's probably also the reason why ArcGIS doesn't suggest any transformation parameters and thus won't reproject my shapefile?).
How can I define my false easting value when I want to re-project my shapefile from epsg:31256 to WGS 84 / UTM zone 33N (epsg:32633)?
Do I miss something?
