i'm guessing that you've got a freighter conversion, with a large fwd cargo door. i would expect that door to react shear. by "move" i expect you mean taxi. in all likelihood i'd expect that there would be little chance of permanent deformation even with a large opening like i think you have. i doubt it'd be considered normal practice, and you should be very careful (move slowly, no bumps or ramps). shoring up the opening, with diagonal braces, would improve the situation plenty.
