Thnx. I did a lot of additional googling and looking up mailarchives, but this 
berkeley-stuff always gave me a headache and I did not manage to find a proper 
documentation or do it on my own.

But I found another solution to export the mailboxes-file on the old machine and 
importing it on the new installation with the ctl_mboxfile-tool.

   * ctl_mboxfile -d  on the old installation
   * empty config/db on the new installation (or just dont copy it from the old one)
   * create an empty mailboxes.db-file on the new installation
   * ctl_mboxfile -u on the new installation

This will create a skipfile-style mailboxes.db - file for me. Closely monitoring 
syslog will help to detect problems.  I put a documentation of my 
migration-process online at http://www.goldfisch.at/knowwiki/migrate_cyrus


best,
peter
