А вот что я нашел в документе под названием "Microsoft Windows Server Update Services 3.0 Overview"

"Upgrade seamlessly from WSUS 2.0 to WSUS 3.0
WSUS 3.0 can be installed on a server that already has WSUS 2.0 installed. The installation process will perform an in-place upgrade that preserves all the previous settings and approvals. The process of upgrading a server hierarchy should start from the central server and continue down the hierarchy. A WSUS 2.0 server can synchronize from a WSUS 3.0 server, but a WSUS 3.0 server cannot synchronize from a WSUS 2.0 server. Upgrading from WSUS 2.0 to WSUS 3.0 is a one-way process; going back to WSUS 2.0 requires that you first remove WSUS 3.0, then reinstall WSUS 2.0."

В общем-то, в первой ссылке всё это по-русски написано )))
