Lotus Quickr software is designed to transform how teams share everyday business content and work together online. And it leverages many existing applications
and content storage systems. Portal Document Manager Components have been removed from the WebSphere Portal 6.1 installation. Lotus Quickr now provides the document management functionality and therefore WebSphere Portal Extend, Express, and the IBM Content Accelerator includes entitlement for Lotus Quickr. This is reflective of the product roadmap for Lotus Quickr which consolidates our document management solution into one product roadmap. There are a number of advantages to this shift in strategy, namely scaling, performance, and modularity.
