Use when upgrading an existing Spring Boot application, for example from Boot 3.x to Boot 4 or to the latest Spring Boot and Java: dependency transitions and starter renames, test annotations such as @MockBean to @MockitoBean, Jackson 3 issues, Spring Modulith 2 or Testcontainers 2 upgrades, code that stops compiling after a version bump, or planning a phased migration. Not for greenfield project creation or isolated repository design.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Spring Boot Migration ## Purpose Use this skill for phased upgrade work on existing Spring Boot applications. This skill adds value through the migration scanner, the Boot 4 / Modulith 2 / Testcontainers 2 reference guides, and a strict migration order that avoids mixing too many changes at once. ## Critical rules - Never migrate blindly. Scan the codebase first. - Never apply every migration at once. Follow phased upgrades. - Treat Spring Boot 4, Spring Modulith 2, and Testcontainers 2 as the intended target stack for this skill unless the user asks for a narrower target. Boot 4's Java baseline is 17; recommend Java 25 for new compile targets but do not force an upgrade past what the migration actually requires. For Java 26+ targets, read `../creating-springboot-projects/references/java-version-policy.md`. - Verify after each phase and stop when failures appear. ## Workflow ### Step 1: Scan the project Use the migration scanner before planning or editing. It reads `pom.xml`, `build.gradle`, or `build.gradle.kts` (whichever the project has) plus Java sources, properties files, and Flyway migrations: ```bash …

How to install
mdr add a-pavithraa/springboot-skills-marketplace/springboot-migration@sha256:2d68625c97ad352bThe line at the top of this page pins the label git:20261025.21a944a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
