Inventor 8 conversion to Solidworks 2009

Hello,

We were told that our parts and assemblies originating in Inventor8 could be
converted to Solidworks 2009 without an issue. I have a user thathas been trying to do this, but the parts are coming over as dumbsolids. Is there anything we can do to get the part constraints tofollow into Solidworks?

Thanks in advance,
