Currently,

The file formats have not changed in such a way for this to be a problem. IIRC, the vector indexing protocols have changed in GRASS7, but this is more of a problem going from 6 to 7 than going the other way.

Raster formats currently remain compatible. There has been discussion about changing these, but this has not happened yet.
