# Migrate Spring Boot 3.5 applications to Boot 4 with staged agent checks

Use the named Spring Boot migration skill to prepare a focused upgrade diff and verify dependency, configuration, JSON and startup behavior.

## Prerequisites

Git; Claude Code or Codex; project Java and Maven/Gradle toolchain

## Installation

Install or set up from the source-backed instructions:

Clone https://github.com/rrezartprebreza/spring-boot-skills. For Claude Code, create /.claude/skills/ and copy skills/spring-boot-4/spring-boot-migration/ there, preserving examples. Start the agent in the application and request a Boot 3.5-to-4 migration using spring-boot-migration. For Codex, use the upstream documented installation adapted to the skill directory supported by your installed runtime. Review instructions and project version requirements before changes.
