OPERATIONAL APPROACH
THE PROJECT
Moving infrastructure is more than moving servers.
A cloud migration changes the environment around an application: networking, access, configuration, data services and the way teams monitor and recover workloads. A reliable plan must account for those relationships before any cutover decision.
This case study sets out OMNISOFT's approach to an OVH Cloud-to-Azure migration. The emphasis is on preparation and evidence at each stage, without assuming a particular customer, workload scale, delivery duration or availability result.
THE CHALLENGE
Keep dependencies visible through the move.
A strong approach makes the difficult parts visible before committing to the next step. These are the considerations that shape the work.
Understand the current estate
Map services, configurations and integrations before choosing the Azure destination.
Protect data integrity
Define how source and destination data will be compared and validated.
Prepare operational ownership
Bring monitoring, access and recovery instructions into the migration plan.
THE APPROACH
Assess first. Prepare before cutover.
The approach begins with a workload inventory and dependency map, then translates those findings into an Azure environment plan. Data validation and application checks provide decision points. A cutover runbook, rollback criteria, monitoring plan and handover package make the transition explicit.
DELIVERY FOCUS
What the approach brings together
Practical capabilities and considerations, organised around the purpose of this case.
Workload assessment
Identify application components, resource needs and service dependencies.
Dependency mapping
Track networking, data flows and integrations that cross environment boundaries.
Azure planning
Map workload requirements to destination services and operating responsibilities.
Configuration review
Account for environment variables, credentials and access requirements.
Data preparation
Define transfer methods, backup expectations and validation checkpoints.
Data validation
Compare source and destination data using agreed checks before acceptance.
Cutover preparation
Document sequencing, decision owners and rollback conditions.
Application checks
Plan functional checks for critical user journeys and connected services.
Monitoring setup
Specify service health signals, alerts and post-cutover observation.
Operational handover
Prepare access notes, runbooks and ownership for the Azure environment.
01 / ENVIRONMENT PLANNING
Connect the source estate to the destination design.
Workload assessment establishes what exists in OVH Cloud and what each service depends on. Azure planning can then address the target environment intentionally, rather than treating the migration as a simple copy of server instances.

Make readiness a decision, not an assumption.
The migration approach separates transfer from acceptance. Data checks and application validation inform cutover readiness; a runbook specifies sequencing and ownership. Rollback conditions should be agreed before the transition begins.

03 / MONITORING AND HANDOVER
Plan for the team operating the new environment.
Monitoring and handover belong in the delivery plan from the start. Service-health signals, escalation responsibilities and recovery instructions help the receiving team understand the Azure environment and the decisions made during migration.
Operational handover · Planning checklistTHE FOUNDATION
Built around preparation, validation and ownership.
Migration readiness depends on the actual estate. The plan should make dependencies, acceptance criteria and operating responsibilities visible without promising an unverified availability or performance outcome.
THE TAKEAWAY
A structured path from OVH Cloud to Azure, with validation and operational readiness at its core.
This case study describes the migration approach; it does not assert a measured deployment result or zero-downtime cutover.
