The dnf package storage is cleared.  PackageKit is independent of

You'd have to ask the PackageKit devs.

rsync them into /var/cache/dnf/[hashed directory entry]/packages/ on the
other systems.  Then run dnf upgrade.  It will reuse the local
packages.  You might have to set dnf to keep rpms in /etc/dnf/dnf.conf,
and manually run dnf clean packages after the update.

There is a setting in the file

# Keep the packages after they have been downloaded

Remove, as root, the hash mark on this configuration option, and
packages won't be kept.
