I don't like any of the suggestions so far, because they take more time than necessary. DB links do ONE ROUND TRIP for every row fetched! That is not efficient. Export is a nightmare of potential failures. I think you can devise the best solution by just copying the database files.
Try this idea on for size:
0. Make sure both versions of Oracle are installed on the host.
This method gives you near zero downtime between kicking the users off the old database and letting them into the new one.
