DevForce EF is built "on top" of ADO.NET EF.  The limitation of 1 EDMX = 1 database still holds.  In DevForce, though, you can include multiple entity data models in a single DevForce "domain" model, as is shown in several of the tutorials. 
 
On the latter part of your question about shifting to a different database - I assume you mean having a single CSDL (conceptual model) with different SSDL (storage model) definitions?  That is doable, and one of the reasons why the EDMX at runtime actually consists of 3 separate resources (conceptual, storage and mapping).  DevForce doesn't do anything to help or hinder this support, and I'd recommend the ADO.NET EF forum (http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=533&SiteID=1) or other MS resources for help on the mechanics of separating the models.

currently for ADO.NET EF, we could make it support for multiple databases by adding respective edmx files.
 
but for DevForce EF, does it support 1 edmx and shift to different databases at anytime?
