KDE 4 Desktop Environment

KDE 4 is a substantial re-work of KDE. An overview is provided with most Distributions and at:

http://www.kde.org

An aspect causing much difficulty is migrating data to the new Personal Information Manager - Kontact

1. essential to copy each users PIM data
   • for earlier releases of KDE 4 see KMail manual, FAQ # 6.11
     • using the commands cp - a or rsync -av
2. contemporary releases have a special command line tool, pimsettingexporter, which starts a GUI window from which all relevant settings AND data can be exported/reimported

Those migrating from KDE 3 to KDE 4 need to pick a "quiet time" because many other apps have been replaced or substantially changed

As of early 2015, KFramework 5, the successor to KDE4 is being implemented concurrently with KDE4
