Just elaborating on the good points Brian has made:
Another interesting article is this one
https://itsfoss.com/upgrade-linux-kernel-ubuntu/
From November 2017. In it, too, the author points out that if you have no need to get the latest, newest kernel ... don't bother. In this last link, the author was looking to, as he says in part
For example, I use
Dell XPS 13 Kaby Lake Ubuntu Edition and I read that
kernel 4.10 will provide a performance boost for Kaby Lake processor. This tempted me to upgrade Ubuntu to latest Linux Kernel but Ubuntu won’t be providing this kernel version anytime soon if it ever does. In such a situation, I could choose to upgrade Linux kernel manually.
So it is more a case of, if you have a need of it, fine.
Downside of this choice you make is that under a newer kernel, support for some of your old hardware may be
dropped.
So I suggest you keep in touch with your PLAN, and modify it where needed, as as necessary.
From both articles, the dead giveaway as to whom produces the product (Ukuu is Ubuntu Kernel Update Utility) is in the references to the PPA (Personal Package Archive) to be added.

This is Tony George, out of India, maker of Timeshift, Aptik, Conky Manager and other good products. So it is likely to be reliable, at the least.
Timeshift already ships as standard with Linux Mint 18.3 'Sylvia' series onwards, also with Linux Lite 4.0. But if you wish access to Timeshift and Tony's
other products, and you are
not using one of those Distros, then I would take the instructions listed in both articles, and add Timeshift to it as follows
Code:
sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get ukuu timeshift aptik aptik-gtk
You may not know it yet but you could use Aptik as well.
In a multibooting situation such as Jeffrey is embarking on, I would also suggest, if using Ukuu, try it out first on a Distro that is
not ruling the roost, ie not the Primary partition on your Grub Menu, then you are less likely to brick your system ... although the installation of a newer kernel
may initiate a change on the leaderboard.
