The Java 21 Migration Playbook: Moving Safely from 11 to 21
About the Event
Are you still running your production workloads on Java 11? With Java 21 established as the go-to Long-Term Support (LTS) release, skipping the "teen years" of Java and making the leap forward is no longer a luxury—it’s a strategic necessity.
But migrating enterprise codebases can feel like navigating a minefield.
Join us for an exclusive, developer-centric tech session where industry experts break down the exact playbook for a seamless transition. We’ll dive deep into how to move your existing codebase from Java 11 to Java 21 safely, efficiently, and without breaking production.
🛠️ What We Will Cover:
The Migration Roadmap: Spotting compatibility issues, tackling deprecated APIs, and handling required code changes before they cause downtime.
Immediate ROI: How to leverage massive performance upgrades (hello, Virtual Threads!) and cutting-edge security improvements native to newer Java versions.
Future-Proofing: Why this migration is a game-changer for your platform’s long-term stability and developer velocity.
🎂 Special Celebration: Java's Birthday!
It’s not all serious tech talk! We are also celebrating Java’s Birthday during this meetup. Get ready for a special cake-cutting session, networking, and plenty of birthday cake. Come for the insights, stay for the celebration!
