Anthropic outlined a six-step framework for planning large-scale, AI-driven code modernization in critical systems.
Anthropic published a guide outlining a six-step framework for organizing large-scale code modernization projects in critical systems using Claude Code.
The framework starts with defining a target state (uplift, transform, or reimagine) and establishing a measurable certificate that every change must meet.
It continues through setting promotion policies for review, preparing infrastructure and teams, building custom agentic workflows, and executing with pilot testing before scaling. The guide stresses that while AI speeds up code changes, organizational preparation and human oversight remain essential in regulated or mission-critical environments.
