GitHub Copilot modernization

Analyzes entire project structure including source code, configuration files, and dependency manifests to identify modernization opportunities, outdated libraries, framework versions, and security vulnerabilities. The agent performs static analysis across Java, Python, and .NET codebases to generate a prioritized remediation roadmap with dependency-aware recommendations for runtime and framework upgrades.

Executes AI-driven code modifications to upgrade runtime versions and frameworks based on project dependencies and detected patterns. The agent analyzes code semantics (not just regex patterns) to rewrite deprecated APIs, update import statements, refactor configuration, and apply framework-specific migration patterns. Transformations are dependency-aware, ensuring changes respect transitive dependency constraints and avoid breaking changes.

Generates detailed documentation of all security-related changes made during modernization, including CVE fixes, deprecated API removals, and security configuration updates. Review documents include change rationale, affected code locations, validation results, and compliance implications. Documentation is formatted for audit trails and can be exported for compliance reporting (SOC2, PCI-DSS, etc.).

Executes project builds and unit tests after code transformations to detect compilation errors, test failures, and runtime issues. When errors are detected, the AI agent analyzes error messages, identifies root causes in the transformed code, and automatically applies fixes (e.g., correcting import statements, fixing type mismatches, updating method signatures). Validation loops until build succeeds or manual intervention is required.

Scans project dependencies for known Common Vulnerabilities and Exposures (CVEs) post-upgrade and identifies vulnerable libraries. In 'Agent Mode', the system automatically generates and applies security patches by upgrading vulnerable dependencies to patched versions, rewriting code to use secure APIs, and removing deprecated security-sensitive functions. Security changes are validated through build and test execution before being presented for review.

Analyzes application architecture, dependencies, and configuration to automatically generate Infrastructure-as-Code (IaC) templates for Azure deployment. The agent infers required Azure services (App Service, SQL Database, Key Vault, etc.) based on application patterns, generates resource definitions with appropriate scaling and security settings, and creates deployment scripts. Output format (Terraform, ARM templates, or Bicep) is configurable based on team preferences.

Generates CI/CD pipeline configurations (GitHub Actions, Azure Pipelines, or other platforms) based on application type, build system, and deployment target. The agent creates workflow files that automate build, test, security scanning, and deployment stages. Pipelines are configured to trigger on code changes and include automated rollback mechanisms for failed deployments.

Provides conversational AI interface within Copilot Chat window for asking modernization questions, requesting specific transformations, and getting step-by-step guidance. Users can ask natural language queries like 'Upgrade my solution to .NET 6' or 'Migrate to Azure' and the agent interprets intent, breaks down tasks, and guides execution. Chat maintains context across conversation turns, allowing follow-up questions and iterative refinement of modernization plans.

Allows users to define custom transformation tasks that encapsulate organization-specific code patterns, naming conventions, or architectural patterns. Custom tasks are stored and reusable across projects, enabling teams to standardize modernization approaches. Tasks can include code templates, validation rules, and post-transformation steps specific to organizational requirements.

Provides UI panel with predefined workflow options (Start Assessment, Upgrade Runtime & Frameworks, Migrate to Azure) that guide users through common modernization scenarios. Each workflow option triggers a sequence of steps: assessment → planning → transformation → validation → deployment. Quickstart panel reduces cognitive load by presenting curated options rather than requiring users to understand all available capabilities.

Analyzes complete dependency graphs including transitive dependencies to understand version constraints, compatibility requirements, and upgrade paths. The agent identifies safe upgrade sequences that respect dependency constraints, detects circular dependencies or version conflicts, and recommends upgrade order to minimize breaking changes. Analysis considers both direct and transitive dependencies across the entire project.
