The biggest problem I think is proving the conversion is "round trip".
I would suggest doing all conversion on the mainframe, and if you need to be 100% sure you could add a step to do the conversion back into a temporary file and compare it with the original.
Any conversion on another platform has a significant risk that you can't convert the result back to the mainframe format. The risk still exists with the mainframe conversion, but at least you can add the comparison step to catch it.
