How do I import my custom-made workspace from InDesign CS5 into InDesign CS6 on the Mac?

I updated from CS5 to CS6 using the Creative Cloud - on my Mac.  Now my previously created custom workspaces aren't showing up.  Yes, I tried copying them from the Library's Preferences folder into the CS6 preference folder, but they still don't show up.  I don't see a way to import workspaces.  I manually re-created my Photoshop workspace, but I don't want to have to do that with InDesign - I did too much work creating it in the first place.  Help, please.
