Yes, some elements in the kmail structure changed from KDE 3 to TDE (maybe 
with 3.5.13?).

I had to do the migration by hand.

I reactivated my oooold Toshiba 3480 that still runs KDE 3.2:

the Mail directory is in home and should be migrated to
 /home/<user>/.trinity/share/apps

I seem to remember there was some file where I could chage where Mail lives, 
but I can't remember.

Anyway, I was able to move my settings - I think I had to re-enter some 
information. But that's rather long ago so my memory may be wrong.
