Upgrading from El Capitan to High Sierra

Hey all, I have a hackintosh currently running El Capitan 10.11.6, and I was wondering if there is a semi graceful way of upgrading to High Sierra without nuking the data.

It's an i5 4690K on a gigabyte GA-H97M-D3H motherboard with a 750 To video card. I believe High Sierra is the latest version is macOS I can install on that due to the video card, but if I'm wrong in that I'd definitely rather go to Mojave.
