We orchestrate end-to-end cloud migrations for enterprise organisations — from initial workload assessment through to post-migration optimisation — with a methodology that has delivered zero-downtime cutovers for systems processing millions of daily transactions. 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.
180+ workloads migrated · Zero unplanned downtime
Phased delivery
Every migration follows a disciplined five-phase cadence, de-risking each wave before the next begins.
Audit current infrastructure, dependencies, and readiness.
Define migration roadmap, wave groupings, and target architecture.
Run proof-of-concept migrations and benchmark performance.
Execute wave-based migration with rollback safeguards.
Tune cost, performance, and governance in the new environment.
Methodology
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.
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.
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.
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.
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.
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.
