What's Included
Cloud migration services cover seven capabilities mapped to a factory methodology rather than ad-hoc per-server execution. Application discovery uses AWS Migration Hub, Azure Migrate, or GCP Migrate with automated dependency mapping and migration-readiness scoring per workload. Migration factory execution runs parallel workstreams — infrastructure, database, and applications — with dedicated cutover engineers and rehearsal cutovers validating procedures before production. Cloud migration consulting is packaged separately for clients who want a decision-ready plan with 7-R classification, target architecture, and funding application before committing to delivery. Database migration uses AWS DMS, Azure DMS, Google Cloud DMS, and native replication with cross-engine schema conversion (Oracle to PostgreSQL, SQL Server to Aurora). Application modernization runs alongside migration where it adds business value. MAP funding access offsets AWS migration costs. Hypercare and transition deliver 30 days of enhanced support after cutover.
Application Discovery & Assessment
Automated discovery with AWS Migration Hub, Azure Migrate, or manual assessment for application inventory, dependency mapping, and migration readiness scoring. Each application gets a recommended migration strategy: rehost, replatform, refactor, retire, or retain.
Migration Factory Execution
Parallel workstreams for infrastructure, database, and application migration with dedicated cutover engineers. Rehearsal cutovers validate procedures before production windows. Rollback procedures tested and documented. Migration waves prioritized by business criticality and complexity.
Cloud Migration Consulting
Advisory-first engagement covering portfolio assessment, 7-R classification per workload, target-architecture design, MAP/AMMP/RMP funding application, and migration runbook authoring. Engage us for strategy only, or extend into delivery — consulting is packaged separately from execution.
Database Migration Services
AWS DMS, Azure DMS, Google Cloud DMS, and native replication for PostgreSQL, MySQL, SQL Server, and Oracle migrations. Cross-engine schema conversion (Oracle→Aurora Postgres, SQL Server→Aurora, Oracle→Spanner, SQL Server→AlloyDB). Parallel-run data validation ensuring zero data loss. Performance benchmarking validates target database meets or exceeds source performance.
Application Modernization
Containerization with Docker and Kubernetes for applications benefiting from portability and scaling. Serverless refactoring for event-driven workloads. Managed database adoption (Aurora, Cloud SQL) eliminating operational overhead. Modernization assessed per application based on business value and technical feasibility.
MAP Funding & Cost Management
AWS Migration Acceleration Program credit application and management. Migration cost projections with cloud TCO analysis. Post-migration FinOps optimization ensuring cloud costs are predictable and optimized from the first month of production operation.
Hypercare & Transition
30-day enhanced monitoring and on-call support after cutover. Performance validation against pre-migration baselines. Issue remediation with accelerated SLA. Smooth transition from migration project to managed operations with documentation handover.
What You Get
A cloud migration engagement ships ten specific deliverables tied to migration governance and operational handover. Application inventory with dependency mapping and migration-readiness scoring shows what's moving and in what order. The per-workload migration strategy assigns 7-R classification — rehost, replatform, refactor, retire, or retain — and justifies each choice. The cloud landing zone deployment provides the target environment with networking, security, IAM, and monitoring before any workload migrates. Migration runbooks document rehearsal cutover procedures and rollback paths. Database migration includes schema conversion artifacts and parallel-run validation reports. Post-migration performance benchmarks compare against pre-migration baselines. MAP funding application and credit management run alongside delivery for AWS migrations. The 30-day hypercare engagement includes enhanced monitoring and accelerated SLA. FinOps optimization tracking and managed-operations transition documentation close out the project formally.

Our 4-Phase Delivery Process
A cloud migration runs through four phases with explicit deliverables, timelines, and exit criteria. Discovery & Planning (2-4 weeks) inventories every application, maps dependencies, classifies workloads under the 7-R framework (rehost, relocate, replatform, refactor, repurchase, retire, retain), builds the wave schedule, and submits MAP funding applications for AWS migrations. Foundation & Landing Zone (2-3 weeks) deploys the target cloud landing zone with networking, security baseline, IAM, monitoring, and CI/CD infrastructure — the production target environment is validated before any workload moves. Migration Execution (4-16 weeks, depending on scope) runs parallel workstreams with rehearsal cutovers per wave, data-validation sign-offs, and production cutover with rollback ready. Hypercare & Optimize (4 weeks plus ongoing) covers enhanced monitoring with accelerated SLA, performance validation against pre-migration baselines, cost optimization, and transition to ongoing managed operations.

What are Cloud Migration Services?
Cloud migration services are end-to-end engagements that move workloads from on-premises data centres or legacy hosting into AWS, Azure, or Google Cloud using a factory methodology — application discovery, dependency mapping, rehearsal cutovers, and documented rollback procedures — designed to eliminate the missed dependencies, untested cutovers, and unclear fallback paths that cause most migration failures. Opsio delivers migrations across the Nordics, UK, and US using AWS Migration Hub, Azure Migrate, and Google Cloud Migrate, with parallel infrastructure, database, and application workstreams and dedicated cutover engineers per workstream. Database migrations use AWS DMS, Azure DMS, and native replication for PostgreSQL, MySQL, SQL Server, and Oracle with parallel-run validation for zero data loss. AWS engagements qualify for Migration Acceleration Program (MAP) funding that offsets part of the assessment, labour, and consumption costs, accelerating the business case for cloud adoption.
Cloud Migration That Delivers Without Drama
Cloud migration is the most consequential infrastructure project most organizations undertake — and the most likely to go sideways. Incomplete application discovery leads to missed dependencies. Untested cutovers cause extended downtime. Unclear rollback procedures leave teams scrambling when problems arise. Opsio's migration methodology eliminates these risks systematically, with built-in security during migration at every stage. Our migration factory approach uses AWS Migration Hub, Azure Migrate, or GCP Migrate for Compute Engine to discover, assess, and migrate workloads at scale. For platform-specific delivery, see our dedicated AWS migration service and Azure migration service pages. We run parallel workstreams — infrastructure, databases, and applications — with dedicated cutover engineers for each workstream. Every migration includes rehearsal cutovers that validate the exact procedure before the production window.
Database migration is where most complexity hides. Our dedicated database migration service uses AWS Database Migration Service, Azure DMS, and native replication tools for PostgreSQL, MySQL, SQL Server, and Oracle migrations. Schema conversion handles PL/SQL-to-PL/pgSQL and T-SQL compatibility. Parallel-run validation confirms data consistency before final cutover, ensuring zero data loss.
Application modernization happens alongside migration when it makes sense. Lift-and-shift gets workloads to cloud quickly, but re-platforming to managed services (Aurora, Cloud SQL, EKS, AKS) and re-architecting to cloud-native patterns (serverless, containers) unlock the real value of cloud. We assess each application and recommend the optimal migration strategy.
For AWS migrations, we leverage the Migration Acceleration Program (MAP) to secure AWS credits that offset migration costs. MAP funding can cover assessment tools, migration labor, and AWS consumption during the transition period. As an AWS Migration & Modernization Competency partner, we help clients navigate the MAP application process and maximize available credits.
Post-migration optimization is not an afterthought. We run a 30-day hypercare period after cutover with enhanced monitoring, on-call support, and performance validation. Once workloads are stable, we transition to post-migration managed services with FinOps cost optimization, security hardening, and DR configuration — ensuring the cloud environment delivers value from day one.
Cloud migration consulting is packaged separately from execution delivery. Before committing to a full migration project, many organizations benefit from a dedicated consulting engagement covering portfolio assessment, 7-R classification per workload, target-architecture design across AWS, Azure, or GCP, and MAP/AMMP/RMP funding application. Clients can engage Opsio for consulting only — producing a migration plan and funding agreement — then take delivery in-house, or extend into full managed delivery. The consulting output includes the wave schedule, per-application migration strategy, cost projections, and risk register.
For Google Cloud specifically, we provide GCP database and application migration covering Cloud SQL, AlloyDB, Spanner, and BigQuery as target platforms. Database workloads migrate via Google Cloud Database Migration Service for MySQL, PostgreSQL, and SQL Server; analytics platforms migrate to BigQuery with explicit cost-modelling to prevent runaway query bills. See our GCP migration strategy guide for the detailed wave pattern and RMP funding specifics.

Cloud Migration Services — FAQ
What do cloud migration services include?
Cloud migration services cover application discovery, dependency mapping, migration strategy selection, landing zone deployment, migration execution with rehearsal cutovers, database migration with data validation, post-migration optimization, and 30-day hypercare support. Opsio migrates to AWS, Azure, or GCP using proven factory methodology.
How long does a cloud migration take?
Timeline depends on scope: 10-20 servers take 4-8 weeks, 50-100 servers take 8-16 weeks, and 100+ server estates take 16-24 weeks. Our migration factory runs parallel workstreams to compress timelines. Every migration includes rehearsal cutovers before the production window. Discovery and planning adds 2-4 weeks upfront.
How much do cloud migration services cost?
Indicative bands, excluding VAT and your cloud bill: Discovery & Planning €8,700–€26,000 (2–4 week engagement); Migration Execution €26,000–€130,500 (full migration, in waves); Post-Migration Managed Ops €4,400–€13,000/mo (ongoing operations). Cross-engine database conversions and modernisation work are scoped per workload. AWS MAP funding can offset part of the initial migration cost for eligible projects; AWS sets the amount per project, and we estimate it during discovery so the business case uses a realistic figure.
What is the AWS Migration Acceleration Program (MAP)?
MAP provides AWS credits and funding to offset migration costs. Eligible projects receive credits for assessment tools, migration labor, and AWS consumption during transition. As an AWS Migration & Modernization Competency partner, Opsio helps clients navigate the MAP application process and maximize available credits. Eligibility depends on migration scope and committed AWS spend. AWS decides the funding amount per project (programme terms: https://aws.amazon.com/migration-acceleration-program/); we estimate it during discovery so the business case uses a realistic figure. We handle the entire application process including workload documentation, business case preparation, and AWS engagement coordination.
How does Opsio ensure near-zero-downtime migration?
We use continuous replication with DMS, CloudEndure, or native replication to keep source and target synchronized during migration. Rehearsal cutovers validate the exact switchover procedure. Final cutover uses DNS changes or load balancer switching for near-instant traffic redirect. Rollback procedures are tested and ready if issues arise during production cutover.
How does Opsio handle migration risk?
Risk mitigation is built into every step: comprehensive discovery prevents missed dependencies, rehearsal cutovers validate procedures before production, parallel-run validation ensures data consistency, rollback procedures are tested and documented, and migration waves are prioritized by complexity so early wins build team confidence.
What happens after migration is complete?
We run a 30-day hypercare period with enhanced monitoring, accelerated SLA, and performance validation. Post-hypercare, we transition to managed operations covering 24/7 monitoring, security, cost optimization, and ongoing infrastructure management. This ensures the cloud environment is optimized and supported from day one.
What does cloud migration consulting include?
Cloud migration consulting is the pre-execution engagement that produces the migration plan: portfolio discovery, 7-R classification per workload, target architecture and platform choice (AWS, Azure or Google Cloud), dependency mapping, the wave schedule, current-state versus target-state cost, a risk register and the funding application (AWS MAP, Azure AMMP or Google Cloud RMP). It is priced as the Discovery & Planning band above. You can take delivery in-house afterwards or extend into managed execution.
