    Back it up, flash the stock ROM, update, root (if there's a root for the version you updated to), restore.

    I'm using the stock ROM. Do I even need to unroot?

    Yes, you need to unroot if you want to do an OTA update or have it flashed. When I rooted my S5, I had to go through several updates to do the final one.

    Even not running a custom ROM, the phone sees it that way for updating when you are rooted.

    Ok, so can I jump from 4.2.2 or am I going to have to do several updates to get to Marshmallow?

    You might have to reflash a kernel and then go through some updates. Let me see what someone else might can tell you. I'm very limited on rooting experience.

    The bad news is I think you are probably going to have to go through several OTA updates. You probably can flash them with Odin, but that is going to take a lot of big file downloads. The other possibility.. Once you unroot, you might can use Kies to update, no guarantee though.

    I don't think Kies will work. It still might see a tampered device. Flashing the stock ROM will probably be the only way to get rid of root completely.

    Oh no I mean Kies after the unroot part. Kies will see root for sure.
