Very very rarely, because it means down time and supporting two systems
at once. Take a look at the australian customs fiasco or the british
passport office disaster to see why (actually almost any large
government IT project where politics dictated 'write new stuff so I can
announce it in parliament').

The smart factory update would occur piece by piece. Starting with the
most pressing problems (ie fastest ROI) and working to a plan that ends
up with the system modular and clean.

You don't turn a steel plant off for a software upgrade.
