I did the inplace upgrade. it took longer than normal. The upgrade to the quality update also took extremely long but succeeded. Immedieatly, a subsequenr Preview Quality Update was offered (26220.7271) and installed successfully but again very very slow.
In short, my problem has been solved. Thank you.
