Hello Michael.

Initial mail might have landed in moderation queue or something like that, at 
least it didn´t get through yet, thus CC´ing to you as well.

This should work.

Which one did you use? You need to use the old one in ~/.kde/share/apps/
kwalletd, not the new one in ~/.config/kwalletd.

You can retry the migration:

Set alreadyMigrated to false again:

%> cat .config/kwalletrc 
[Migration]
alreadyMigrated=true

Restart kwalletd. One way is to log out and log in. There is another way which 
works during a session, but I am not sure how it worked. Maybe you can just 
quit kwalletd5 process and start it again.
