I've successfully pulled off most of such a majority re-write but a key driver - but not the only was that the legacy language the existing system was implemented in had lost virtually all traction in the local and global market. Mostly only expensive contractors coming out of pension availabile and on top of that the custom libraries required us to recruit the 10 percent of that segment. Any new hires straight up refused to pick it up as they accurately deemed it career suicide.
