Others have mentioned the DBMS_FILE_TRANSFER package, but I would answer with a different question - why would you even want to do this?

Think about it from a different perspective. What do you gain from having the two environments dissimilar? If you have a standardized configuration (be that one way or the other - ASM/OMF or non-ASM/non-OMF), then you don't need to remember two different configurations.

I'd need to see a valid reason for doing so is what I'd guess I'd be saying. Now a valid reason might exist - I just can't think of what it would be.
