The first thing you'll need to do is backup your working system from recovery. Back-up to your external sd card so you will have something to fall back on, just in case something goes wrong. Ya never know with these phones
But flashing a kernel will not delete anything off your phone fyi. Never happen to me with all the kernels I've flashed 😎.
