THE 00FELIX WORKFLOW
3 steps to modernizing Spring Boot applications.
Most Spring Boot 2.7 applications aren't broken. That's exactly why upgrades get postponed. But every month on a legacy framework increases technical debt, security exposure, and engineering effort.
00felix automates the entire modernization workflow, from identifying upgrade blockers to validating the final build.
[ STEP 01 ]
Discover what's preventing the upgrade.
Understand exactly what's blocking migration from Spring Boot 2.7 and Java 8.
- Analyze dependency trees and transitive packages
- Identify Java 17 compatibility issues
- Detect javax → jakarta migration requirements
- Trace vulnerable dependencies back to framework versions
- Build a complete modernization plan
[ STEP 02 ]
Upgrade Spring Boot automatically.
00felix performs the changes required to move your application onto a modern platform.
- Spring Boot 2.7 → Spring Boot 3.x
- Java 8 → Java 17
- Refactor breaking API changes
- Convert javax imports to jakarta
- Resolve dependency conflicts automatically
[ STEP 03 ]
Validate the upgrade and eliminate risk.
Every upgrade should result in a working application and measurable security improvement.
- Rebuild the application automatically
- Execute tests and validate runtime compatibility
- Verify dependency resolution and package integrity
- Eliminate vulnerable transitive dependencies
- Generate a pull request automatically
- Measure CVE reduction before and after modernization
