==> Configuration conversion is possibly required

    Since you're upgrading from an older version, you may need to
    convert your configuration file (i.e. /etc/cherokee/cherokee.conf)
    to be compatible with the new cherokee version.

    Converters have been installed in /usr/share/cherokee/converters
