What problem does it solve? Migrating applications between frameworks or versions requires manually rewriting dozens of configuration files, property mappings, and environment settings, which is error-prone and often leaves deprecated or broken settings behind. ## Core Features & Use Cases - Property Mapping and Transformation: Converts configuration files between formats (properties, YAML, XML, JSON) with source-to-target property mappings, such as Quarkus to Spring Boot. - Environment-Specific Migration: Updates dev, test, and prod configurations while preserving environment parity and externalizing secrets. - Build and Security Config Updates: Migrates Maven/Gradle build settings, Spring Security configurations, and Dockerfiles to target platform conventions. - Use Case: When upgrading from Spring Boot 2.7 to 3.2, use this Skill to update application.yml properties, rewrite the SecurityConfig to the SecurityFilterChain pattern, bump the Java version in pom.xml, and produce an execution_configuration_changes.md report. ## Quick Start Migrate all configuration files in this project from Quarkus to Spring Boot format and document the property mappings and validation results.
