Which mail storage format (mbox,maildir,sdbox,mdbox) are you using and is it stored on NFS? Would you provide your "doveconf -n" output for dovecot 2.0.13, please? You might also have a look at imapsync[1] for clean mass migration from one architecture to another. Regards Daniel [1] http://imapsync.lamiral.info/
