Spring Boot 3 to 4 Migration
Migrate in controlled stages. Keep behavior changes separate from the framework upgrade.
Establish the baseline
- Upgrade to the latest Boot 3.5 maintenance release.
- Run unit, slice, integration, startup, and migration tests before changing the major version.
- Remove Boot 3 deprecations and record all explicitly versioned dependencies.
- Compare the Boot 3.5 and Boot 4 dependency-management reports.
- Verify Spring Cloud and other portfolio release-train compatibility independently.
Prepare for Boot 4
