mixed lead free and non lead free production

Hi We are in the process of developing a lead free product to be used in a non lead free selective soldering machine, i do have concern in these, and hope you guy can share your experienced expert opinion:

1. What does it take to convert to lead free in the flux - heat - solder process??

2. Can we reuse the same machine? My point here is that the non lead free process has already coated the machine interior ( exhaust, internal flow ) with leaded component, and by conversion to lead free are we containminating the lead free product from the previous production?
