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.
