Comment # 3 on bug 1213222 from Stefan Hundhammer

BTW also in that forum thread you mention a migration path that I am not sure
is supported: From Leap 15.4 to 15.5 to TW.

You might get lucky, and it might work; but it might also fail in spectacular
ways. And you are now suggesting workarounds for a totally self-made problem.

The beauty of Linux and Open Source in general is that you can get creative and
do novel things. You can take charge; you are in total command of your system.
But that comes at a cost, and that is taking responsibility if it fails.

So please don't dump that responsibility into somebody else's lap.
