Our migration practice eliminates the false choice between speed and safety, applying parallel-run validation, automated rollback triggers, and dependency-sequenced wave planning to protect business continuity throughout. Clients consistently achieve 30–50% infrastructure cost reductions within twelve months of migration completion. [Home](https://claritasone.com/) › [Services](https://claritasone.com/services) › [Cloud Services](https://claritasone.com/services/cloud-services) › **Cloud Migration** ## Overview Cloud migration is not an infrastructure project — it is a business transformation programme that, executed correctly, unlocks the elasticity, global reach, and innovation velocity that on-premises architecture fundamentally cannot provide. The risk is real: migrations that lack rigorous dependency mapping, validated rollback plans, and executive sponsorship routinely overrun budget and timeline while creating the very disruption they were designed to avoid. Claritas migration engagements begin with a quantified business case — total cost of ownership modelling, risk-adjusted migration sequencing, and board-level governance checkpoints — ensuring your investment is protected and your leadership team retains full visibility throughout. Our cloud-agnostic practice has delivered migrations to AWS, Azure, and GCP, with multi-cloud and hybrid architectures designed for organisations where regulatory constraints preclude full public cloud adoption. ## Our Approach ### 1. Cloud Readiness Assessment & Business Case We inventory your application portfolio, map dependencies, classify workloads by migration complexity, and model the total cost of ownership in the target cloud environment. A formal business case is presented to your executive sponsor before any migration activity commences. ### 2. Migration Strategy & Wave Planning The 6R framework (Rehost, Replatform, Repurchase, Refactor, Retire, Retain) is applied to every workload based on business value, technical complexity, and regulatory constraints. Migration waves are sequenced to resolve dependencies and protect critical revenue-generating systems. ### 3. Proof of Concept & Validation A representative subset of workloads is migrated first to validate tooling, network configuration, and performance baselines. This de-risks the programme and produces the evidence your CTO needs to authorise full-scale migration with confidence. ### 4. Scaled Migration Execution Migration waves are executed using automated tooling (AWS MGN, Azure Migrate, or custom orchestration) with parallel-run validation ensuring the migrated environment produces identical outputs to the legacy system before traffic is cut over. All cutovers occur within pre-agreed maintenance windows with explicit rollback triggers. ### 5. Optimisation, FinOps & Decommission Post-migration, we apply rightsizing analysis, Reserved Instance or Savings Plan purchases, and architectural optimisations that convert the performance of migrated workloads into realised cost savings. Legacy infrastructure is decommissioned only after a validated stability period. ## Capabilities - Application portfolio assessment: dependency mapping, risk scoring, and 6R classification - Total cost of ownership modelling and cloud financial business case development - AWS, Azure, and GCP migration tooling: MGN, Azure Migrate, and Database Migration Service - Database migration: homogeneous and heterogeneous engine conversions - Network architecture design: VPC, ExpressRoute, Direct Connect, and hybrid connectivity - Parallel-run validation and automated reconciliation frameworks - FinOps implementation: rightsizing, commitment-based discounts, and cost governance - Compliance validation: data residency, sovereignty, and regulatory alignment ## Outcomes | Metric | Value | | --- | --- | | Unplanned downtime incidents in migrations we have led | **Zero** | | Median infrastructure cost reduction 12 months post-migration | **40%** | | Workloads migrated across AWS, Azure, and GCP | **180+** | | Average time from assessment to first production cutover | **16 wks** | ## Next Step **The cost of delaying your cloud migration compounds every quarter.** Engage our migration practice for a no-obligation cloud readiness assessment that quantifies your migration risk, projected savings, and the fastest safe path to the cloud. → [Get a proposal](https://claritasone.com/get-a-proposal) · [Contact us](https://claritasone.com/contact) --- View the live page: About Claritas One: · Contact: · All pages:
