The most Questions are “Could you tell me how to upgrade from Pisi Linux 1.2 to Pisi Linux 2.0”
The answer is very simple: There are many major differences between 1.2 and 2.0. The only way is to do a fresh install.
The differences between KDE 4 (Pisi Linux 1.series) and KDE 5 / Plasma 5 (Pisi Linux 2.0 are very large.
You have in KDE 4 the kde4libs they are not in KDE 5 as example, and so goes it further a lot of Dependencies and libs from KDE 4 are not in KDE 5
You can read this article and see what is new in KDE 5 http://arstechnica.com/information-technology/2014/08/kde-plasma-5-for-those-linux-users-undecided-on-the-kernels-future/1/
The best Way is a new install from Pisi Linux 2.0 Alfa7
Have fun to do it
