Frequently Asked Questions

FAQPage Schema
How to install Spring Boot 4 Migration Skill?▼

Run `npx skills add adityamparikh/spring-boot-4-migration-skill --all -g -y` in your terminal to install it globally.

How to migrate a Spring Boot 3 app to Spring Boot 4?▼

Ask your agent to migrate the project, and it walks you through 9 ordered phases covering build files, properties, Jackson 3, Security 7, and testing. A verification script confirms each step with PASS/FAIL/WARN checks.

Can I migrate from Spring Boot 2.7 directly to 4?▼

Not directly. The skill first guides you from 2.7 to 3.5 (Java 17 baseline, Jakarta namespace, Security 6), then chains into the 3.5 to 4.x migration.

Does it support gradual enterprise migrations?▼

Yes. A gradual strategy uses compatibility bridges like spring-boot-starter-classic and spring-boot-jackson2 so large codebases can migrate in independent tracks over time.

Does it work with Kotlin, Maven, and Gradle?▼

Yes. It covers Java and Kotlin projects on both Maven and Gradle, and checks minimum toolchain versions before starting the migration.
