If the headlights are perfect in both cars then its a direct swap along with the lens and the housing. just 4 screws each headlight housing.
If not get the projectors and headlight bowls from the car with projectors and switch it to the one with the halogens. But this would mean there wont be a place for the ballasts to attach in the halogen housing.
Pretty simple swap.
Both will need the LCM to be coded though.
Find someone with a bmw scanner PA soft or buy one. Not expensive.
