Just set a transform in geographic coordinates, and GeoServer
will find the path to convert from UTM to geographic and vice versa.
Have you tried this, and played with the reprojection console?
4314,4258=PARAM_MT["NTv2", PARAMETER["Latitude and longitude
difference file", "BETA2007.gsb"]]
And, if you needed to -or you didn't want GeoServer to pick any
transform step for you-, you could always define the whole transform
path, from end to end:
31467,25832=CONCAT_MT[INVERSE_MT[PARAM_MT["Transverse_Mercator",
PARAMETER["semi_major", 6377397.155],
PARAMETER["semi_minor", 6356078.962818189],
PARAMETER["central_meridian", 9.0],
PARAMETER["latitude_of_origin", 0.0],
PARAMETER["scale_factor", 1.0],
PARAMETER["false_easting", 3500000.0],
PARAMETER["false_northing", 0.0]]],
PARAM_MT["NTv2", PARAMETER["Latitude and longitude difference file",
"BETA2007.gsb"]],
PARAM_MT["Transverse_Mercator",
PARAMETER["semi_major", 6378137.0],
PARAMETER["semi_minor", 6356752.314140356],
PARAMETER["central_meridian", 9.0],
PARAMETER["latitude_of_origin", 0.0],
PARAMETER["scale_factor", 0.9996],
PARAMETER["false_easting", 500000.0],
PARAMETER["false_northing", 0.0]]]
