Frequently Asked Questions

FAQPage Schema

How to install github-copilot-modernization?▼

Run `npx skills add microsoft/github-copilot-modernization --all -g -y` in your terminal to install all skills in this collection globally.

How to upgrade a Java app to Java 21 automatically?▼

Start the modernization workflow and describe your goal in plain language, such as 'upgrade this app to Java 21'. It handles Spring Boot upgrades, javax-to-jakarta migration, and deprecated API replacement automatically.

Can it migrate my application to Azure?▼

Yes. It migrates Java and .NET applications to Azure services like Service Bus, Azure SQL, Redis, Key Vault, and Application Insights, with Managed Identity authentication by default.

How does it fix CVE vulnerabilities?▼

It scans Maven, NuGet, and npm dependencies against known CVE databases, upgrades vulnerable packages to patched versions, then rebuilds and re-scans to confirm the fixes.

Can I enforce company standards during migration?▼

Yes. Place markdown policy files in a rulebook folder defining target architectures, upgrade standards, and guardrails. These rules override default recommendations in every generated plan.
