📋 PLAN OVERVIEW & CRITICAL SUCCESS FACTORS

Migration Success Formula:

Foundation (40%) + Parallel Deployment (25%) + Systematic Testing (20%) + Validation Gates (15%) = 99% Success

Key Principles:

• ✅ Never proceed without 100% validation of current phase
• ✅ Always maintain parallel systems until cutover validated
• ✅ Test rollback procedures before each major step
• ✅ Document everything as you go
• ✅ Validate performance at every milestone

Emergency Contacts & Escalation:

• Primary: Jonathan (Migration Leader)
• Technical Escalation: [TO BE FILLED]
• Emergency Rollback Authority: [TO BE FILLED]
