    The following should be considered when importing the management packs into a management group which does not have OpsMgr SP1 installed:
    • The Library, Windows 2000 Server and Windows Server 2003 specific management packs can be imported into a management group that does not have OpsMgr 2007 SP1.
    • The Windows Server 2008 specific management packs are not supported, and will not import, into a management that does not have OpsMgr 2007 Service Pack 1 installed. This is due to the fact that monitoring of Windows Server 2008 is not supported without Service Pack 1.
