Migrating from KDE3.5 to KDE4.2

First, it is possible to just copy your old .kde dir to .kde4. Some things didn’t work for me and anyway it’s a good opportunity to do some housecleaning, so I decided to try and import data instead (and keep the old .kde3 dir in case I need it later).

Konqueror: import bookmarks from 4.2 works fine (bookmarks -> edit bookmarks -> file -> import -> kde2/3 bookmarks, select KDE_35_FOLDER/share/apps/konqueror/bookmarks.xml.

Kaddressbook (contacts): export them in kde3 into one big vcard file, import in kde4.

Kmail: Use the import mail options. I quickly gave up on finding the files for the identities and just set them up again in 4.2 instead.

Kgpg: replaced by kleopatra. Just copied ~/.gnupg over and everything Just Worked.

Kopete: The only thing I wanted over was the history. Copy over the files and directories under ~/.kde/share/apps/kopete/logs/ to the ~/.kde4 dir. In Kopete for KDE4.2 it uses a new MSN-plugin, which uses a different folder for logging. I just moved the logfiles from MSNProtocol to WlmProtocol.

Akregator: I first just used file -> import feeds and found the rss-file under the old kde3 folder. Works well, however I have a few articles marked as important so to get these over I copied the Archive-folder over as well (.kde/share/apps/akregator/Archive), which worked fine.

The other programs just requires minor adjustment and I didn’t import the settings.
