Millions of lines of legacy code sit dormant across enterprises — costly to maintain, impossible to evolve, and a barrier to cloud adoption. What if AI agents could do the heavy lifting of modernizing them?

In this hands-on workshop, we tackle the full Application Modernization pipeline using two powerful tools: GitHub Copilot Modernization CLI for AI-driven automated code analysis and transformation, and Spec2Cloud for spec-enabling legacy repositories through Spec-Driven Development. Together, they form an agentic modernization pipeline that turns legacy codebases into cloud-native, spec-enabled, maintainable systems — with minimal manual effort.

Every attendee works on a real legacy repository and takes it through the full modernization journey:

🔍 Analyse: Run GitHub Copilot Modernization CLI to assess the codebase, identify modernization candidates, and generate a transformation plan
📋 Spec-Enable: Apply Spec-Driven Development principles to generate API contracts and specifications from legacy code using Spec2Cloud
🤖 Agentic Transformation: Use AI agents to apply spec-driven refactoring patterns, modernize dependencies, and update configuration for cloud targets
☁️ Cloud-Ready: Validate the modernized codebase against cloud-native patterns and prepare it for container or serverless deployment
🔄 CI/CD Integration: Wire the modernization pipeline into GitHub Actions for continuous modernization at scale
Attendees will leave with a modernized repository, a reusable agentic pipeline, and the skills to apply this workflow to their own legacy systems.

Prerequisites: Laptop with Git, GitHub CLI, and .NET or Java SDK installed. A GitHub account with Copilot access. Setup instructions provided in advance.
