Basically when you migrate a project from A to B, your best result would be to have B that works as good as A (people don't want change, people don't want new bugs). Since you most of the time didn't code A, were not responsible for it, etc. and, at the same time, are expected to understand it thoroughly (you got the fg code after all), you're expected to do at least as good as A. So you're B will be compared to A and will always be seen as inferior. How treacherous.
