Problem solved, but the solution is a little bit dirty...
I created the backup as a binary file with the web frontend, transfered it to the new server with the latest version and imported the file via web interface. This way seemes to work, but why is the console way with ejabberdctl so buggy?!

I'll contact the Debian packager about this problem.

The tutorial that you refer ( http://www.ejabberd.im/migrate-host ) is only for old 2.0.x. I've put in strong letters that 2.1.x admins better follow the ejabberd Guide.

In your case, right now, follow the tutorial in the ejabberd Guide.
