I'm moving from Windows to Linux and currently have Fedora KDE 44 running well. I've customized my terminal, desktop theme, and general KDE setup, so I'd like to know how to back up those settings and restore them quickly after a reinstall instead of configuring everything manually.
For major Fedora releases, such as upgrading from version 44 to 45, is an in-place upgrade the usual approach, or is a fresh installation preferable? I'd also like advice on removing applications and cleaning up dependencies safely. If I uninstall a program, how can I tell which dependencies are still needed by other software?
Finally, I'm trying to keep package management straightforward. I generally prefer RPM packages and will use Flatpaks when appropriate, but I'm less familiar with AppImages and Snaps. What are the practical advantages and drawbacks of each, especially regarding permissions, updates, and system maintenance?

RPMs integrate best with Fedora’s package database and dependency handling, so they’re usually the simplest choice for system software. Flatpaks are useful for desktop applications because they bundle their runtime and can be given limited permissions, though they use additional disk space and may not integrate perfectly with every system feature.
AppImages are generally portable executable files with little installation work, but updates and desktop integration are often manual. Fedora doesn’t include Snap as a native package format, so using it adds another package-management system. If simplicity is the priority, sticking mainly with RPMs and selectively using Flatpaks is a reasonable approach.
Most personal configuration is stored under your home directory, including hidden files and folders. Backing up `/home/your-username` will preserve much of your desktop and application setup. You can also use a KDE configuration backup tool such as Konsave for a more focused export.
It’s usually unnecessary to back up cache directories such as `~/.cache`, since they can become large and are regenerated. After reinstalling, restore the useful configuration files gradually if possible, because old settings can occasionally conflict with newer software.
For Fedora, upgrading in place is generally the normal approach. You can move from one release to the next using Fedora’s upgrade process rather than reinstalling every time, and it usually preserves your applications and settings. It’s still wise to make a reliable backup first and wait a couple of weeks after a new release if you want to avoid early bugs.
For unused RPM dependencies, `sudo dnf autoremove` is the usual command. Review the packages it proposes before confirming. DNF tracks package requirements, so it should not remove a library still required by another installed RPM. Be more cautious with software installed manually or without package metadata.
That clears things up, especially the distinction between package-managed dependencies and software installed manually. I’ll make sure to review the list from `dnf autoremove` instead of accepting it blindly.
