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
