I've been meaning to write this guide for a little while now, but I've only just gotten around to it. Basically, I had wanted to try the N preview, but TWRP didn't play nice with it, so until now, it has been impossible to run N with encryption, root, and without wiping your data. In the interest of full disclosure, I found this solution while down a Reddit rabbit hole in a very short post at the end of some thread that I've been unable to find again, so I can't take full credit. Many thanks to this random Redditor.
I originally posted this solution in another thread, which I can't link to since I'm on mobile at the moment (I'll try to update later) but the tl;dr version is this: you have to wait to flash the vendor image from N until you're all done with twrp, but other than that, it's just like you're updating with a monthly security patch.
Actually hold on if you're reading this, I'm going to try to save this and go grab my laptop to do a proper job...
