Unless you've explicitly uninstalled all your ports yourself they should still be there when you install the newest version of macports. You are then free to view all installed ports and uninstall/reinstall them as you see fit.

... it is not a matter of 'seeing fit'. Unless you want ongoing problems, the only correct thing to do is to reinstall *all* your ports....
