I have a new installed opensuse 11 system with kde4 and an old parition with the home and .kde inside my home with its kde3 configfiles.
How can I now make kde4 use these .kde configfiles and convert them into its own .kde4 configfiles?
cp .kde/share/apps/<folder>/* .kde4/share/apps/<folder>
for each folder you want to copy or open Konqueror
check View>Hidden Files
Window>Split View
Navigate to .kde/share/apps in one window and .kde4/share/apps in the other and then copy the relevant files across folder by folder
Some folders may not be relevant so a global copy is not recommended.
You may have to extend the above commands if KDE3 and KDE4 are on different partitions but the principle is the same.
