Due to security constraints, CentOS 6 cannot manage CentOS 7 appliances. This is primarily because CentOS 6 does not support the ciphers required by CentOS 7. To mitigate potential security risks, we've discontinued the management of CentOS 7 appliances using CentOS 6.
As an alternative, the Uniview portal can effectively manage CentOS 7 appliances at no additional cost. This platform offers all the necessary controls to facilitate your operations.
For any further inquiries or concerns, or if you do not have access to Uniview please reach out to your account manager.
