IF - All the services are correctly modelled, and
IF - You modify the IFC export properties
You CAN export MEP objects from AutoCAD MEP in an IFC format, and then import the IFC to Revit MEP.
There are issues with this process though.
The majority of objects will be "in-place" families, INCLUDING system families like Ducts and Pipes, so the valus of the trasfer process is limited. In fact you'd probably (if using the Autodesk suggested workflow), be going in the other direction - from Revit to AutoCAD.
Personally, I'd like to be using Revit MEP for the entire process, I can only see Autocad having a limited shelf life for this type of application.
