Are you just changing the genres or are you also introducing some 2004 elements with namespace and all? TVA's atrocious practice of changing namespaces when they change versions could introduce all manners of problems for implementations if the upgrade isn't planned.
Since the genre schemas are backwards compatible, the initial change would probably be cosmetic in just changing the 2002 to 2004 in the data. New genres introduced in the 2004 schema will eventually be used.
In fact, 2004 descriptors are already in use for AudioPurpse in the audio description information for the simple reason that they didn't exist in the 2002 classification schema!
