We present the adiabatic transportation of a Bose-Einstein condensate from a standard magnetic trap to a dielectric surface located 3.6 mm below. The vertical shifting of the trapping potential is obtained by ramping up an additional homogeneous magnetic field in 100 ms. It is the first stage of the adiabatic transfer of the condensate from the initial 3D magnetic trap into a 2D evanescent light trap sitting at the dielectric surface.
