Dual Maintenance and Retrofit During Transformation
Covers the hard problem of supporting production on the old landscape while building the new one: why dual maintenance exists, how an N+1 project landscape sits beside the maintenance landscape, how production fixes are retrofitted into project systems, how freezes keep retrofit volume down, and how retrofitted changes are tested and tracked until nothing is left behind at go-live.
