I too keep /home on a separate partition, and have thought about keeping 
the same /home partition intact across upgrades, but I have never dared to 
do so. So my situation is different enough from yours that I still need to 
ask the following question more explicitly:

Dotan suggests carrying over only ~/.kde[4]/share/apps/<appName>. Since 
e.g. kmail is represented in both .kde and .kde4, presumably I should 
carry over both appName directories. But apps also have subdirectories 
~/.kde[4]/share/config/<appName>, so there are altogether four appName 
subdirectories needed for each  kde app. I'd bother copying at all only 
for kmail and kaddressbook, because that is where imprtant data are.

But when v11.2 and kde4 install kmail and kaddressbook, will they actually 
make use of these directories that came from kde3?

Good plan. Thanks much.
