Easy! All you do is unplug one switch and plug in the other.
How do I set up an Xbox Adaptive Controller (XAC)?
If you’re using a Windows 10 machine or an updated Xbox, you simply plug the controller into your device.
If you are using a PlayStation, you’ll need an adapter called a TitanTwo
If you’re using a Nintendo switch, the best Option is currently the Magic-Ns Wireless adapter from Mayflash
Adapters that don’t work:
8bitdo wireless controller adapter for Switch - As of 6/20/2018 This device does not work wirelessly, there is no wired option. There have been other people reporting issues connecting Xbox controllers wirelessly. I will test this out in the future.
Fastsnail Controller converter - This works great with the Xbox Elite controller however it does not work with the XAC, my guess is that it doesn’t understand how to handle USB C and only knows how to use USB Micro
What joysticks work with the Xbox Adaptive Controller (XAC)?
There are currently a very limited number of joysticks that work with the XAC.

Extreme 3-D Pro
A fully-fledged computer flight joystick compatible with the XAC
