Absolutely. You are going to get a ton of useless data in the transfer. Maya transfers everything even if it does not know what to do with it.

To be sure to clean out any hidden or orphaned nodes select all the nurbs surfaces only and then export the selection to a new file. This should clean out all the garbage nodes and leave you with a file that just contains the nurbs geo.

I think that will leave you all you need. Generally when I transfer stuff the nurbs surfaces are all I really want.
