A year later, a different team is tasked with replacing a legacy system with a new one. The team asks the Executive when the legacy system needs to be replaced. "Oh, well the legacy system still works, so we don't have a hard date. But it should be soon." Four years later, the team is still working on replacing the legacy system. The Executive comes to them and says, "Looks like we won't be using that system anymore, so we can sunset the replacement."
