The SharePoint team has released a new procedure on how to move SharePoint databases across servers. Until they are able to do so, it is available in the Microsoft download site at: http://www.microsoft.com/downloads/details.aspx?FamilyID=65686896-c171-46a8-a95f-54f43ad79952&displaylang=en
There are 2 separate procedures and both can be downloaded on the same page. One for moving databases to a server with the same name, and one for moving databases to a server with a different name.
Remember, This procedure is meant to move “ALL” SharePoint Databases to a new server. However, they are not able to publish it on TechNet at the time.
