    Center can automatically upgrade the software to the latest version

    without requiring any login credentials to the system

    : If all assets use the same

    login credentials, you can apply a single set to all assets for the

    upgrade process. The log-in credentials are the same ones used for

    asset discovery and management, which are stored in the Plan
