What does Google actually think of your old domain at the moment?
Have a look in your Google webmaster tools - does it mention duplicate content in the "content analysis"?
Is your old site in Google's index?
Does it rank well for any terms (especially the site name without the www)?
If it's in the index and ranks for some of your terms and the content analysis looks ok then you will probably be fine.
