There’s a guide here: https://communityblog.fedoraproject.org/rebasing-fedora-silverblue-to-kinoite/

The poster there had some problems because of the packages they layered, but as you can see everything goes smoothly if you don’t layer anything and even those problems are pretty easy to fix.

For info, I only had neovim and zsh layered when I rebased and nothing broke.

But the beauty is that on the bootloader you have a list of the deployments, so if you break something, you can rollback to a previous system image with one selection!
