Cloud Migration: 5 Critical Mistakes You Must Avoid

Why Do Cloud Migrations Fail?

According to Gartner, over 30% of all cloud migrations fail due to inadequate planning. The technical implementation is rarely the problem, it is strategic misjudgments at the beginning of the project.

Mistake 1: Lift & Shift Without Analysis

Simply copying VMs to the cloud does not deliver cloud benefits. Without adapting the architecture, you often end up paying even more than on-premise, with equal or worse performance.

Mistake 2: No Cost Modeling

Cloud costs behave fundamentally differently from on-premise costs. Without a detailed cost model that accounts for traffic patterns, storage consumption, and compute requirements, you will face unpleasant surprises on your monthly bill.

Mistake 3: Security as an Afterthought

The shared responsibility model of the cloud requires a shift in thinking. IAM policies, VPC configuration, and encryption must be planned from day one, not as the last step before going live.

Mistake 4: No Rollback Strategy

Every migration needs a Plan B. We always plan a phase of parallel operation during which both the old and the new infrastructure are production-ready.

Mistake 5: Forgetting the Team

Cloud technologies require new skills. Without training and gradual onboarding, your team will become the bottleneck, no matter how good the infrastructure is.
