1. What storage servers is your current systems running, if its just an NFS,
then all you need to do is jus mount them on exadata servers and use RMAN and migrate to ASM on exadata.
2, If you are already using a ASM. Then you have two options.
1. Use a RMAN active duplicate( This will be very slow with I/O being a big bottle neck.
2. Take a backup on NFS filesystem and then use RMAN duplicate.

DBFS in Exadata is for flat files in the first place. Files you process with External Tables resp. SQL*Loader, that is.
Data Pump dumpfiles can (and should) be placed on ASM diskgroups directly - no need for DBFS here.

We're looking into doing this by a DB link so we don't need to export to filesystem at all but not there yet.We use datapump over a db link so we do not need an intermediate file system and have a 1 step approach.
