<p>Hi everyone,</p>
<p>I need to migrate many user mailboxes from an NFS folder to a new
NFS folder, both mounted on the same Dovecot server (2.2.27).</p>
<p>Once migrated, users will connect to a new Dovecot server
(2.3.4.1).</p>
<p>I would like to know how to use <i>doveadm backup</i> (or sync?)
instead of <i>rsync</i> as I noted that after migration with
rsync I have duplicates and some e-mails marked as unread.</p>
<p>What is the correct way to achieve this?</p>
<p>Thanks</p>
<p>Cheers<br>
</p>
