One piece. At the driver level this not a big scary change. This is just a change with widespread effect. It should be no worse than enabling a very revealing new compiler warning. Every fix should be purely mechanical. There should be no need at all to think to get it right (unless things are broken today and we just don't see it.). Yes typo's and the like will happen. There will be issues. But 99% of them will be the code doesn't compile, for an obvious reason. Eric
