The bad news is you have to remove the "feet" from the roof rack (or at the very least 2 of them on either the front or back). That involves CAREFULLY prying off the covers, unscrewing the bolts that hold the feet on, and then using a small hex wrench to detach the feet from the long bars. Once that's done, you can slide the cross bars out of the long bars. Then you get to re-assemble it.
It's a pain.
