It is easy to replace Notes to Exchange, if Notes main use is sending and receiving mail.
For the apps, a small code in Notes, sometimes pages of code in any other enviroment. And I doubt that there is any other software that can fully replace Notes.
In real life, I have seen examples, mail clients are replaced, Notes applications freeze, no version upgrades are made, but Notes simply keeps on existing. In many cases for years. Servers may be reduced. But just it. In the long run, I don't think that anything might be achieved with that change. :-(
