Cloud Migration Services

End-to-end cloud migration services — from initial assessment and migration strategy through execution and post-migration optimisation — for workloads moving to AWS, Azure, or GCP with minimal business disruption.

Why Businesses Need This Service

Cloud migration is a technically complex, business-critical programme. The failure modes are well-documented: migrations that stall mid-way, unexpected costs from lift-and-shift approaches, performance degradation in the new environment, and security regressions from rushed configurations. Cloud Migration Services provide the methodology, tooling, and execution expertise to migrate successfully while managing risk at every stage.

Our Implementation Process

A systematic approach that ensures timely delivery and exceeds expectations

Step 1

Migration Assessment

Discover all on-premises workloads, map application dependencies, assess cloud readiness, classify workloads by migration strategy (6Rs), and build migration waves prioritised by complexity and business value.

Step 2

Foundation Build

Establish cloud landing zone with network connectivity, IAM structure, security baseline, and monitoring before first workload migration. Get the foundation right before migrating anything.

Step 3

Pilot Migration

Migrate the first wave of low-risk, non-production workloads to validate tooling, processes, and the target architecture. Learn and adjust before migrating critical production systems.

Step 4

Production Migration

Execute production migrations in planned waves with defined cut-over windows, parallel-run periods, and validated rollback procedures. Maintain business continuity throughout.

Step 5

Optimisation & Closedown

Post-migration: optimise right-sizing, increase cloud-native service adoption, decommission on-premises infrastructure in verified tranches, and deliver final cost and performance comparison vs baseline.

Example Success Story

See how we've helped businesses achieve success with cloud solutions

Client Challenge

A regional bank needed to exit a data centre lease renewing in 18 months. 140 servers, 35 applications, and 8TB of data needed to migrate to Azure without disrupting banking operations or creating compliance gaps.

Cloud Solution Implemented

We ran discovery and dependency mapping, classified all 35 applications by migration strategy, built an Azure landing zone meeting banking compliance requirements, migrated non-production environments first, executed production migrations in 8 waves over 12 weeks with zero-downtime database cutovers, and decommissioned the data centre 6 weeks ahead of lease expiry.

Business Results

140 servers migrated in 12 weeks with zero unplanned downtime

Data centre lease exited 6 weeks ahead of deadline saving £240,000

Infrastructure costs reduced 41% post-migration vs data centre costs

100% compliance requirements maintained throughout migration

All 35 applications validated and performing within SLA in Azure

Frequently Asked Questions

Common questions about Cloud Migration Services

The 6Rs framework categorises workloads by migration strategy: Rehost (lift-and-shift, migrate as-is), Replatform (migrate with minor optimisations, e.g. move to managed database), Refactor/Re-architect (redesign for cloud-native), Repurchase (replace with SaaS), Retain (keep on-premises for now), Retire (decommission). Choosing the right R for each workload is the most important migration planning decision.
