Cloud migration is the most complex technology project most organizations will undertake. Done well, it reduces infrastructure costs by 30–50%, eliminates hardware refresh cycles, and enables capabilities that on-premise systems simply can't match.
Phase 1: Discovery and Assessment (Weeks 1–4)
Catalog everything using automated discovery tools. Classify each workload using the 6Rs framework: Rehost, Replatform, Repurchase, Refactor, Retire, or Retain.
Phase 2: Foundation and Landing Zone (Weeks 4–8)
Build your cloud foundation before migrating anything — account structure, IAM, network architecture, security controls, logging, and monitoring.
Phase 3: Migration Waves (Weeks 8–24)
Migrate in waves, starting with low-risk, low-complexity workloads. Each wave: test in staging, migrate to production, validate, decommission on-premise.
Phase 4: Optimisation (Ongoing)
Implement right-sizing, reserved instances, and auto-scaling from day one. Set up cost anomaly detection. Review and optimize monthly.
