Succeeding at your cloud migration: the SME checklist

Published on July 5, 2026by Pierre Coulanges2 min read

Moving to the cloud is no longer reserved for large groups. For an SME, the cloud promises flexibility, security and reduced infrastructure costs. But a poorly prepared migration can turn into a headache. Here is a checklist to succeed.

Why migrate to the cloud?

  • Flexibility: you adjust your resources to your activity, without over-investing.
  • Security and continuity: backups, redundancy and disaster recovery handled by professional infrastructures.
  • Accessibility: your teams access tools everywhere, an asset for hybrid work.
  • Controlled costs: less hardware to buy and maintain.

The key steps of a successful migration

1. Map the existing environment

Before migrating, you need to know what you’re migrating: applications, data, dependencies, volumes. This mapping avoids nasty surprises.

2. Choose the right strategy

Not all applications migrate the same way: simple move (“lift and shift”), adaptation, or redesign. The right choice depends on the criticality and age of each application.

3. Secure and ensure compliance

The cloud isn’t less secure — provided you properly configure access, encryption and backups. GDPR compliance (data location, subcontractors) must be verified from the start.

4. Migrate in stages

A “big bang” migration is risky. Proceed in waves, starting with non-critical applications, to learn and adjust.

The quick checklist

  • [ ] Inventory of applications and data
  • [ ] Analysis of dependencies and volumes
  • [ ] Choice of provider and data location
  • [ ] Security plan (access, encryption, backups)
  • [ ] GDPR compliance check
  • [ ] Staged migration plan with testing
  • [ ] Recovery plan in case of incident
  • [ ] Team training and support

Pitfalls to avoid

  • Underestimating change management: technology is only half the work.
  • Forgetting recurring costs: the cloud must be managed to avoid bill drift.
  • Neglecting reversibility: keep control of your data and an exit route.
