Cloud
Cloud migration for businesses without compromising business continuity
A phased approach, featuring an actual inventory, pilot testing, and a short, planned cutover window.
Request migration assessmentThe starting point
The justified fear of migrating
Halting invoicing, ERP, or production for two days is not an option. This is why many companies postpone migration until the hardware fails and the decision is made in a rush.
- Servers out of support and without spare parts guarantees
- Legacy applications with undocumented dependencies
- Extremely limited or non-existent downtime windows
- Lack of a rollback plan if something goes wrong
Our response
Migrating with a safety net
Before moving anything, we establish the inventory and the dependency map. We design the target environment, migrate a pilot, validate with key users, and only then execute the cutover, always with a defined reversion plan.
Most failed migrations do not fail because of technology, but because of dependencies that no one documented before starting.
Benefits
What you gain with Cloud Migration
Minimum cutover window
Prior replication and final synchronisation.
Rollback plan
The source environment is maintained until the destination is validated.
User validation
Functional testing before signing off the migration.
No cost surprises
Sized according to measured, not estimated, consumption.
Documentation delivered
Architecture, access, and procedures in writing.
Post-migration support
Monitoring and fine-tuning after the change.

Frequently Asked Questions
Common pre-engagement questions
- How long does a migration take?
- It depends on the number of servers, data volume and application dependencies. A small environment can be resolved in a few weeks; one with ERP and connected sites requires a wave-based plan over several months.
- Can systems be migrated without downtime?
- Operations do not stop during the bulk of the process: replication is carried out while systems are running. There is typically a short cutover window for final synchronisation, usually outside productive hours.
- What happens if something fails during the cutover?
- The rollback plan is activated: the source environment remains available until the functional validation of the destination is complete.
- Can we migrate only a part?
- Yes. It is common to start with backup and secondary environments, leaving the production core for a second phase once the model has been validated.
