After upgrade the server to 6.0, login 8073/dmc or 8073/dac successfully. But failed to login DPS(Provisioning Server).
Please check the das5.log (\Program Files\Deepnet DualShield\tomcat\logs), it reports the "handshake error". In this case, you will need to upgrade the DualShield Framework.
Note: This issue happens particularly for version 5.9.5.0611. If you upgrade straight from 5.9.5.0611 to 6.0. It is recommend that you upgrade the framework first before upgrade to 6.0.
