It outlines a phased migration approach with the goals of minimizing complications and reducing user confusion. Key phases include rolling out the new SAP NetWeaver 2004s tools, migrating web templates and workbooks, and migrating broadcasting security. The document also compares the BEx design-time and runtime tools between SAP BW 3.x and SAP NetWeaver 2004s, describing how queries, web applications, and other objects can be used across both platforms or migrated to the new tools.
