Assess Java Applications for Cloud Migration and Modernization

Ayan Gupta demonstrates how to use the GitHub Copilot app modernization extension to assess a legacy Java codebase and produce an actionable modernization plan, including cloud readiness findings, Java upgrade issues, CVEs, and coverage insights.

Overview

The video walks through running an AI-assisted modernization assessment for a legacy Java application using the GitHub Copilot app modernization extension.

Key areas covered:

• Getting a high-level view of a legacy Java codebase using GitHub Copilot.
• How the assessment works under the hood:
  • Static analysis
  • Rule-based inspection
• Interpreting the “Mission Control” dashboard, including:
  • Cloud readiness issues
  • Java upgrade issues
  • Known vulnerabilities (CVEs)
  • Coverage-related signals
• Creating custom modernization tasks for edge cases the tool doesn’t handle out of the box.
• Turning an initial “where do we start?” situation into a categorized view of risk and effort, with a clearer path to modernization.
