The configuration data is stored at
~/.config/calibre/
Make a backup. This contains all plugins and configutations.
Configuration of custom columns and other library-related things are stored at the Calibre Library directory. I want to believe you already have a good backup of this directory. Make another one ;-)
The thing is, that the old Calibre is most probably installed somewhere in /usr/local/bin or in other place where other GUI programs installed by your distro are located.
When you install Calibre Library from the Calibre.org site, it will be installed to the /opt/calibre directory. So you do not have to uninstall anything, the old Calibre will remain in place.
Before installing the new version of Calibre go to terminal and type
which calibre
to see where your Calibre as packaged by a distribution is installed. You will most probably see something like
/usr/bin/calibre
Now, have a look at this file. It is most probably just a symlink pointing you to the "real" calibre binary
ls -l /usr/bin/calibre
You should always install Calibre from the official site

The vast majority of Linux distributions do not keep up with the fast pace of official Calibre updates.
I think that your update will be seamless. Just make a backup "just in case".
When I am migrating to the new version of Linux distribution or to the new disk or a new PC, I just copy the Library directory and the ~/.config/calibre/ directory and install Calibre from the official site. I have never had a problem.
I have even migrated from the version of Calibre as packaged by a distribution to the official one in the past.
