Microsoft Commerce Server 2009 – Release Candidate, formerly known as Commerce Server 2007 code name “Mojave”, is the final pre-release of the next version of Commerce Server.

Commerce Server 2009 delivers the ability to increase your business reach by making it possible to sell via multiple channels using an out-of-the-box shopping site, SharePoint Commerce Services, and the Multi-Channel Commerce Foundation. The new out-of-the-box shopping site leverages SharePoint Commerce Services, which provides a gallery of ASP.NET 3.5 Web Parts, a comprehensive e-commerce shopping feature-set, and technology integration between Commerce Server and SharePoint technologies. The Multi-Channel Commerce Foundation provides a new unified, extensible run-time programming model for Commerce Server, including new run-time e-commerce capabilities.

This Release Candidate is the last pre-release before final release of the product. While this version contains a limited “use in production” license, it is a time-bombed release and you will need to acquire the product through your Volume Licensing, MSDN or ISV channels in the near future. This pre-release requires an installed version of Microsoft Commerce Server 2007 Enterprise or Standard Edition. This release is not compatible with Commerce Server 2007 Developer Edition.

You must uninstall all previous Commerce Server CTP versions. Leveraging a clean system that has never had a previous version of a Commerce Server CTP installed upon it is strongly recommended.

The Commerce Server 2009 product documentation will automatically be installed as part of setup and will replace the existing Commerce Server 2007 documentation set. Once installed, you can review the documentation by going to Start> All Programs> Microsoft Commerce Server 2009> Documentation> Commerce Server Documentation.
