You can convert between any RHEL-like distro by changing your repos, swapping/removing a few key packages (release, branding, subscription-manager certs if converting from RHEL) and then running distro-sync to make sure your other packages match your repositories. This can be done transactionally via the "shell" subcommand which allows you to run multiple commands in a single transaction.

YUM/DNF can do the whole thing without much fuss.
