When a cloud migration crosses the 60% threshold, the easy workloads are gone. What remains are the systems that resisted the first wave: data warehouses with undocumented downstream consumers, the Friday-night batch job nobody can stop, the application that runs on a forgotten Windows Server 2008 box.
The fix is not technical — it's organizational. We see three repeating patterns: ownership ambiguity (no single team accountable for the legacy system), risk asymmetry (the team that has to migrate it has nothing to gain), and budgeting cliffs (year-two cloud spend balloons before savings appear).
In this post we lay out a 90-day reset that re-establishes accountability, re-prices remaining workloads, and gets the program past the 80% line.
