There is a lot of different possible choices, all depending on how fast you want to get there, how much you are willing to spend, how much fun you wanna have along the way, how safe you want to be and who your friends are.
Taking it to the extreme, strictly speaking, some extra fuel would get you there in one go. The airplane may not have the tanks for it, but if those were to be installed and the airplane stripped for every non-essential item except for you in your underwear, it would be able to take off with the necessary fuel in extra weight. They don't call it super versatile for no good reason. But okay, so much for the nonsense.
The most common route is over the north Atlantic, which for the PC 24 basically pivots around Reykjavik. The PC 24 is a certified aircraft and therefore by no means less safe than any airliner. It's being flown along that route fairly often, primarily for ferry flights. Having a PIC who's done it before is highly recommendable. Many pilots get nervous flying over large bodies of water for good reason and the extra catch to this route is the extreme cold. Rescue gear back and forth, to survive ditching in a PC 24 in the north Atlantic requires having some serious guardian angels.
If you want to get an impression of what flying that route is like, there is a documentary of an actual ferry flight available on YouTube, plus various videos of the same trip in other aircraft, including a single engine Cessna and a good old Dakota. It gives you a fair idea of what to expect along the way in the sense of accommodations and services.
