Packages migrating to a systemd unit file from a SysV initscript
When updating from a package containing a SysV initscript to a package containing a systemd unit file, we "start-over fresh" with default start and stop policy from the new package, and do not migrate what the user had previously configured. For this reason, you can simply use the above scriptlets and not worry about converting the sysv information to something relevant to systemd.
Only migrate between releases
Packages are strictly forbidden from migrating to systemd within updates to a Fedora release because migration will reset the user's choices about whether to start or stop the service. Migration is only allowed between Fedora releases.
