F-11->F-12 while using kde-testing?

[Laurent Rineau]

Dear list,

I have tried to upgrade my F-11 laptop to F-12, using preupgrade (using 
upgrade to Rawhide). All went well, but Qt and kde packages were not upgraded. 
The F-11 installed versions came from kde-testing.

The result is that, for example, libssl.so.8 was upgraded to libssl.so.10, and 
deps of libQtNetwork were broken. My upgraded laptop was able to box to F-12, 
but the KDE session could not be launched.

I have manage to launch "yum update", and updates from kde-testing are now 
been downloaded, and it should fix all those problems.

I am surprised that preupgrade allows the upgrade whereas it was foreseeable 
that the upgraded set of packages will have broken deps. I am also surprised 
that preupgrade do not use the configured repos in /etc/yum.repo.d/, which 
mostly are usable both within F-11 and F-12.

What is the recommended way to upgrade from F-11 to F-12 if kde-testing (or 
even kde-unstable) is in use? I have another (less experimental) machine that 
I would like to upgrade.
