I've migrated databases from different platforms using transportable tablespaces. According to Metalink documents 1166564.1 and 77523.1: "Oracle transportable tablespaces are the fastest way for moving large volumes of data between two Oracle databases".
So with this info, I'd suggest you try that route.
Check out the following document too : « 10g : Transportable Tablespaces Across Different Platforms [ID 243304.1] » as it seems to apply in your case.
I've also wrote a very precise how to document to achieve exactly what you're trying to do. So let me know if you're interested.
