F30 Halogen and Xenon headlight swap

Hi guys,

So I may be selling my car and purchasing a relatives as it is lower mileage and auto. Both are identical with the exception of mine having xenons and his halogen.

In order to swap is it just a matter of unplugging and changing the lights or are there any additional components that will be needed for the xenons to work on the previous halogen model and vice versa?

Any advice will be appreciated.

Thanks in advance
