🚨 Critical Blockers (Must Fix Before Migration)

🟠 HIGH PRIORITY

1. Service Optimization: n8n needs to move from jonathan-2518f5u to fedora
2. Monitoring: No monitoring stack deployed
3. Service Dependencies: Not validated

⚠️ Important Notice

DO NOT PROCEED WITH MIGRATION until all critical blockers are resolved. The current 75% readiness indicates significant progress with comprehensive analysis completed, but infrastructure gaps must be addressed for successful migration.

Estimated Preparation Time: 1-2 days for critical issues, 1 week for comprehensive readiness Total Migration Duration: 6 weeks as planned (with optimized end state) Success Confidence: HIGH (with preparation), MEDIUM (without)
