In this video the speaker demonstrates the features and updates of the Quest On Demand Migration Desktop Update Agent (DUA). The DUA agent is designed to replace the current client update agent and offers support for Outlook, OneDrive for Business, Microsoft Teams, and Microsoft 365 app subscriptions. The new agent provides real-time reporting, a centralized management interface, and supports multiple devices and modern authentication methods. The demo showcases the process of migrating a user's applications, such as Outlook, Teams, and OneDrive, to a new account.
