About LiveUpdate Administrator (from Symantec LiveUpdate™ Administrator User's Guide)
LiveUpdate Administrator is an enterprise Web application that allows you to manage updates on multiple internal Central Update servers, called Distribution Centers. Using LiveUpdate Administrator, you download updates to the Manage Updates folder, and then send the updates to production distribution servers for Update clients to download, or to testing distribution centers, so that the updates can be tested before they are distributed to production. You can download and distribute updates on schedule, allowing you to create a low maintenance, reliable system that can be set up once, and then run automatically. Updates can also be manually downloaded and distributed as needed.
Updates are downloaded from an external site to an internal LiveUpdate Administrator server. From there, the updates can either be sent immediately to a production distribution center to be downloaded by Update clients, or sent to a testing center, so that the updates can be tested. Once the updates have passed your testing requirements, they are sent to the production center, on a schedule you determine.
