Blender to Maya, exporting bones constraints properly?

Good evening,

I’m making a shed for the game "farming simulator 17 "and I ve got some bones in blender to animate some doors but Giants editor (the software of the developper) does’t support rigging or animations from blender but only from Maya so I’d like to export my model in maya with bones constraints etc properly and then export it to Giants editor .So I exported my model in fbx in Maya but bones don’t work in Mya as in blender, I guess the constrait has not been exported properly or I did Something wrong, have you already exported bones in maya properly or is it not possible (I exported in BInary, do I have to export with the other format?)

P.S: sorry for my bad English, I’m french:D
