Sorry adamw, could you clarify what you mean. Are you talking about a problem totally replacing 3.5 with 4.0 or with having the two running in tandem and then upgrading?
The problem is with porting KDE3 user settings and data (mail etc.) into KDE4. Since many KDE3 settings are not relevant to KDE4 and since some of the config and data files are structured differently, Mandriva has opted to store KDE4 settings and data in a separate directory from KDE3 (~/.kde4 as opposed to ~/.kde). (This also allows a user to run both KDE3 and KDE4 on a single system.)
Most people, however, will probably have been using KDE3 in previous releases and will install and use the default KDE4 in 2009.0. In order for these people to upgrade it is necessary to port the KDE3 settings and data to KDE4.
This requires that a process be developed to identify those settings and data which can be safely ported and write a script for doing so. I believe that is the work that is ongoing to which Adam referred.
If you are already using KDE4 on your existing installation, then there should be no problem with upgrading (nor should there be a problem if you are using KDE3 and intend to continue to use KDE3 in 2009.0).
