Upgrade Paths
Migration guidance between major versions — breaking changes, effort estimates, and tips.
Breaking Changes
- Java 17+ required (drops Java 8, 11)
- javax.* → jakarta.* namespace migration (JEE 9+)
- Spring Framework 5 → 6 (major API changes)
- Spring Security: WebSecurityConfigurerAdapter removed
- Actuator endpoint path changes
- Embedded server configuration changes
- Properties and YAML configuration key renames
Migration Notes
This is the hardest Spring Boot upgrade in history. Use OpenRewrite with the spring-boot-3 recipe set to automate javax→jakarta and config changes. Spring Boot Migrator CLI handles many patterns automatically. Test thoroughly — the Security config overhaul catches most teams.
Breaking Changes
- Virtual threads support (Project Loom, Java 21+)
- SSL bundle reloading
- RestClient as modern alternative to RestTemplate
- Observability improvements (Micrometer)
- Docker Compose support improvements
Migration Notes
Smooth upgrade. Virtual threads are opt-in (requires Java 21). RestClient is optional — RestTemplate still works. Run tests and update dependencies.
Breaking Changes
- Structured logging support out of the box
- Enhanced MockMvcTester for testing
- Improved Docker Compose lifecycle management
- ClientHttpRequestFactoryBuilder for HTTP clients
Migration Notes
Non-breaking release. All new features are additive. Update spring-boot-starter-parent version and test.
Version Risk Assessment
Evaluate risk factors before choosing a version for production.
| Version | EOL Risk | CVE Risk | Ecosystem | Cloud Support | Overall | Recommended Action |
|---|---|---|---|---|---|---|
| Spring Boot 2.7 and below | Critical | High | Unsupported | Legacy | Critical | Past EOL — no patches, javax namespace is dead end |
| Spring Boot 3.0 / 3.1 | Critical | Medium | Degrading | Full | Critical | Past EOL — upgrade to 3.3+ |
| Spring Boot 3.2 | High | Low | Maintenance | Full | High | OSS support ended — upgrade to 3.4 |
| Spring Boot 3.3 | Medium | Low | Active | Full | Medium | Supported until Nov 2025 |
| Spring Boot 3.4 | Low | Low | Active | Full | Low | Current stable — recommended |
| Spring Boot 3.5 | None | Low | Growing | Full | Low | Latest — adopt when ready |
Risk combines EOL status, Java version requirements, Spring Security posture, and ecosystem support. Assessed as of March 2026.
