Kmail migration – for the record

Transfer mail and settings to another computer (or another user account on the same machine)

Solution: The messages are typically in ~/.kde/share/apps/kmail/. For very old installations of KMail, the messages can also be in ~/Mail. Note that KMail uses hidden sub-directories inside that directory, so you need to make sure to copy hidden directories as well.

For settings you will need to copy the following files:

  • ~/.kde/share/config/kmailrc,
  • ~/.kde/share/config/mailtransports, (since KDE 4.0)
  • ~/.kde/share/config/emaildefaults and
  • ~/.kde/share/config/emailidentities .

Your address book is usually stored in ~/.kde/share/apps/kabc/. Calendar data is in ~/.kde/share/apps/korganizer

Be aware that some distributions use ~/.kde4 instead of ~/.kde/ for their KDE configuration data.

From version 4.4 you may have some Akonadi-controlled entries that also need to be kept. Add to the above list -

  • Everthing under ~/.local/share/
  • Everything under ~/.config/akonadi/.
  • ~/.kde/share/config/nepomukserverrc
  • Everything under ~/.kde/share/apps/nepomuk/ (KAddressBook stores contact groups in Nepomuk.)
