ColdFusion Version Comparison

Comprehensive comparison of ColdFusion 2025 against legacy versions to help you evaluate upgrade benefits, understand performance improvements, and plan migration efforts.

Quick Decision Guide

✅ Upgrade Immediately If:

  • Running CF 11, 2016 (end of life, critical security risk)
  • Compliance requirements demand current security patches
  • Performance issues under current load
  • Planning new features requiring modern Java/containers

⚡ Upgrade Soon If:

  • Running CF 2018 (approaching end of support)
  • Wanting JDK 17 performance benefits (30-40% improvement)
  • Need cloud/container deployment capabilities
  • Require advanced security features (MFA, session hardening)

📅 Plan Upgrade If:

  • Running CF 2021, 2023 (stable, supported)
  • Want latest features and performance optimizations
  • Preparing for long-term platform modernization
  • Evaluating package management with cfpm

Key Takeaways

🚨 Urgent Action Required

If running CF 11 or 2016, migration is critical due to end-of-life status and unpatched security vulnerabilities. Plan immediate migration path.

⚡ Performance Gains

CF 2025 delivers 2.5x throughput improvement and 5x faster response times compared to CF 11, with 50% lower memory usage due to JDK 17 and G1GC optimizations.

🔒 Security Enhancements

CF 2025 includes MFA support, advanced session security (SameSite cookies), comprehensive security headers, and container security hardening not available in legacy versions.

🐳 Modern Deployment

Official container support, cfpm package management, and cloud-native features make CF 2025 suitable for Kubernetes and modern CI/CD pipelines.
