    <p>I need to move from one mount point to multiple mount points and
      I'm searching for the best strategy.</p>
    <p>Right now my take is to script a rsync of the folders that need
      moving, change dovecot config and restart. <br>
    </p>
    <p>In order to do this I need to know in advance what users will end
      up on the newly added mount point.</p>
    <p>Thank you for 'doveadm user'. This seems to be the appropriate
      tool.</p>

                    I want to ask if any of you has done a migration
