Do you

1. Stick to the X pattern on tire rotations (front right to back left, front left to back right and vice versa)

2. Move the rears to the fronts and fronts to the rears (back right to front right, back left to front left)

3. Move the rears to the fronts and put the front's on the opposite side on the rear? (rears to the front, and right front goes on back left, left front to back right)

4. Move the fronts to the rears and put the rears on the opposite sides on the front (fronts directly back, and left rear to right front, right rear to left front)

5. Just take it to a shop because you're lazy

I was told for AWD you perform #3, but was going to measure all tread depths and move them to #1 (x pattern) as this seems most logical to me.

#3. The front tires are more sensitive to changes in orientation, especially reversed rotation, so when you reverse the rotation you do it on the rear. That applies to AWD, RWD and FWD.

Obviously you need to be conscious of the tread depth difference limitations on X drive to avoid winding the transmission up.

[Billfitz]

The difference between a new tire and bald wouldn't particularly bother the xDrive electronic clutch system, let alone a modest difference. Not that I recommend it, of course.

[FaRKle!]

I do #3 for all square tire rotations (unless the tires are directional).

Ok, so I ended up just doing #3 anyways, I had one question though. I know the manual shows to jack up the car on the differential (closer to the front) but I just jacked it up at the point where these two braces met, had no issue and felt more comfortable having it there as the bolts can sit inside the jack pad.
