What is AWS Migration Services?

AWS migration service is the structured process of moving workloads, databases, and applications from on-premises or third-party cloud environments to Amazon Web Services using AWS-native tooling, defined methodology, and partner-managed execution. Standard scope covers six consistent responsibilities: discovery and dependency mapping using AWS Migration Hub and Application Discovery Service; server replication and cutover via AWS Application Migration Service (MGN), which performs automated lift-and-shift with minimal downtime; database schema conversion and continuous replication through AWS Database Migration Service (DMS), supporting homogeneous and heterogeneous migrations across Oracle, SQL Server, PostgreSQL, MySQL, MongoDB, and MariaDB; network architecture redesign including VPC topology, Transit Gateway, and Direct Connect provisioning; post-migration validation covering performance baselines, security posture with GuardDuty and AWS Security Hub, and IAM policy hardening; and ongoing modernization toward containerized or serverless targets using ECS, EKS, or Lambda. Infrastructure-as-code for repeatable environments is handled through Terraform or AWS CloudFormation. Migrations structured under the AWS Migration Acceleration Program (MAP) follow three phases — Assess, Mobilize, Migrate and Modernize — and qualified engagements receive credits covering up to 25 percent of eligible migration spend, materially reducing total project cost. Tooling complexity scales with workload count; enterprise programs involving hundreds of servers routinely span three to twelve months depending on data volume and application interdependencies. Leading providers in this space include AWS Professional Services, Accenture, Deloitte, and Wipro. Opsio holds AWS Advanced Tier Services Partner status with an AWS Migration Competency, has completed 3,000-plus workloads since 2022 under a zero-downtime methodology, and delivers engagements through its Sweden headquarters and ISO 27001-certified Bangalore delivery centre with 24/7 NOC coverage and a 99.9 percent uptime SLA, making it a focused option for mid-market and Nordic enterprise buyers.

Migrate to AWS with an AWS Competency Partner

An AWS migration demands far more than simply copying servers to the cloud. Organizations need deep expertise in AWS-specific tooling, network architecture, identity management, and data transfer strategies to avoid costly missteps. Without proven methodology, failed migration projects lead to extended downtime, data loss, budget overruns, and eroded stakeholder confidence that can set your entire cloud initiative back by years. As an AWS Migration and Modernization Competency Partner and MAP Competency Partner, Opsio has migrated 3,000+ workloads to AWS. We leverage the AWS Migration Acceleration Program (MAP) — a proven cloud migration program built on a three-phased framework: Assess, Mobilize, and Migrate & Modernize. MAP provides up to 25% credits on eligible migration spend, along with tools, training, and expertise from the AWS Partner Network. Two program tiers exist: MAP Lite for projects with $100K–$500K annual recurring revenue (ARR), and standard MAP for $500K–$10M ARR. We combine MAP funding with AWS Application Migration Service (MGN) for automated server replication and AWS Database Migration Service (DMS) for database migration — all executed with our zero-downtime methodology.

Every AWS migration starts with comprehensive assessment using AWS Migration Hub and Application Discovery Service. We inventory all servers, databases, and application dependencies, categorize workloads by optimal migration strategy — rehost, replatform, or refactor — and build the detailed business case with projected ROI, TCO analysis, and realistic timeline that stakeholders can trust.

The landing zone is the foundation of every successful AWS migration. We deploy a Well-Architected landing zone with multi-account structure using AWS Organizations, centralized logging with CloudTrail, security baseline with GuardDuty and Security Hub, networking with Transit Gateway, and IAM policies with least-privilege access — all defined in Terraform for reproducibility.

Common AWS migration challenges we solve: application dependencies that nobody documented, databases with stored procedures requiring platform-specific conversion, network latency issues between on-premises and AWS during cutover, licensing complexity for Windows and SQL Server workloads, and team anxiety about production cutover windows. Opsio's methodology addresses each systematically.

Evaluating aws migration services cost? Assessment and planning runs $5,000-$15,000. Migration execution ranges from $25,000-$100,000+ depending on workload count and complexity. AWS MAP funding can offset 50%+ of these costs — making enterprise-scale migration financially accessible. We provide fixed-price quotes after assessment.

Service Deliverables

AWS migration services span six capabilities tied directly to the AWS Migration Acceleration Program (MAP) framework. AWS Migration Assessment uses Migration Hub and Application Discovery Service to inventory servers, databases, and dependencies, classifies each workload by optimal strategy (rehost, replatform, refactor), and produces the business case with TCO and timeline. AWS MAP funding access — as a MAP Competency Partner — secures up to 25% credits on eligible migration spend, with MAP Lite supporting $100K-$500K ARR projects and standard MAP supporting $500K-$10M ARR. Server migration uses AWS Application Migration Service (MGN) for continuous block-level replication with non-disruptive test environments. Database migration handles both homogeneous (Oracle to Oracle on RDS) and heterogeneous (Oracle to Aurora PostgreSQL) via DMS with AWS SCT for schema conversion. Application modernization to ECS/EKS, Lambda, Aurora, or DynamoDB runs alongside migration where it adds value. Post-migration optimization includes Well-Architected review across all six pillars.

Our 4-Phase Delivery Process

The AWS migration sequence follows AWS's official three-phase MAP framework with an additional optimization phase. Assess (MAP Phase 1, 2-4 weeks) discovers your environment with Migration Hub, maps dependencies, assigns migration strategy per workload, qualifies you for MAP funding, develops the business case, and produces a readiness assessment. Mobilize (MAP Phase 2, 2-4 weeks) designs the target AWS landing zone, deploys it with Terraform, plans migration waves, trains your team, secures MAP credits, and migrates a pilot workload to validate the approach end-to-end. Migrate & Modernize (MAP Phase 3, 4-12 weeks) executes server replication via MGN and database migration via DMS with zero-downtime cutover, parallel validation, and tested rollback ready — application modernization happens alongside migration where it adds value. Optimize & Operate (2-4 weeks plus optional ongoing) runs Well-Architected review, cost optimization with Compute Optimizer, security hardening, and operational handover.

Industries Served by Opsio

AWS migration patterns vary significantly by industry, and Opsio adapts wave design and tooling accordingly. Enterprise migrations are typically multi-application programs with MAP funding scoped at the program level — wave planning aligns with budget cycles, datacenter contract expirations, and stakeholder governance committees. SaaS companies need zero-downtime migration for customer-facing platforms with deployment-pipeline compatibility maintained throughout the cutover, plus performance validation against pre-migration baselines before stakeholders sign off. Healthcare migrations require HIPAA-compliant data handling with encryption in flight and at rest, BAA documentation for every AWS service touched, and audit trails throughout the migration window. Financial services run regulated workload migrations under SOC 2 and PCI DSS frameworks with documented change management, evidence trails for regulators, and explicit segregation of duties between migration and production access roles. Same MAP framework, different compliance overlays.

AWS Migration Services — MAP Funded, Zero-Downtime — FAQ

How long does AWS migration take?

Simple lift-and-shift of 10-20 servers takes 4-8 weeks including assessment, landing zone setup, and validation. Complex migrations with database restructuring, application modernization, and multiple environments typically require 3-6 months. Enterprise programs with 100+ workloads may span 6-12 months with wave-based execution. We provide detailed timelines after assessment with milestone-level granularity, so your stakeholders have clear visibility into progress and can plan business activities around each migration wave. Every timeline includes buffer for testing and validation to ensure quality is never sacrificed for speed.

What is the AWS Migration Acceleration Program?

The AWS Migration Acceleration Program (MAP) is a proven cloud migration program built on a three-phased framework: Assess (evaluate readiness and build the business case), Mobilize (set up the cloud foundation, train teams, and pilot initial workloads), and Migrate & Modernize (execute at scale and optimize). MAP provides up to 25% credits on eligible migration spend, plus access to AWS Partner Network tools, training, and expertise. Two program tiers exist: MAP Lite for projects with $100K–$500K annual recurring revenue, and standard MAP for $500K–$10M ARR. As a MAP Competency Partner, Opsio handles the entire application process — workload qualification, credit procurement, and compliance reporting — so you maximize your funding while following the structured methodology that has powered thousands of successful enterprise migrations worldwide.

How much does AWS migration cost?

Assessment and planning: $5,000-$15,000. Standard migration of 10-50 servers: $25,000-$60,000. Enterprise migration of 50+ servers: $60,000-$100,000+. AWS MAP funding can offset a significant portion of these costs. We provide transparent fixed-price quotes after assessment with detailed scope, timeline, and risk mitigation included. All pricing is fixed after assessment, so there are no surprise charges during execution, and MAP credits are applied to reduce your out-of-pocket investment wherever qualifying workloads are identified.

Can you migrate databases to AWS?

Yes. We use AWS DMS for both homogeneous migrations (Oracle to Oracle on RDS, SQL Server to SQL Server on RDS) and heterogeneous migrations (Oracle to Aurora PostgreSQL, SQL Server to PostgreSQL). AWS Schema Conversion Tool handles stored procedure and function translation. Continuous replication enables zero-downtime cutover with tested rollback capability. Each database migration includes comprehensive data validation — row counts, checksums, and application-level testing — to verify complete data integrity before confirming the cutover and decommissioning the source system.

What AWS migration tools does Opsio use?

We leverage the full AWS migration toolkit: Migration Hub for centralized tracking, Application Discovery Service for inventory, MGN (Application Migration Service) for server replication, DMS for database migration, Schema Conversion Tool for heterogeneous database moves, Transfer Family for file transfer, and CloudEndure for disaster recovery validation during transition. We select the optimal combination of tools for each workload rather than applying a one-size-fits-all approach, ensuring each migration uses the most efficient path to AWS.

What is a landing zone and why do I need one?

A landing zone is the foundational AWS environment that receives your migrated workloads. It includes multi-account structure with AWS Organizations, centralized logging, security baseline with GuardDuty and Security Hub, networking with Transit Gateway, and IAM policies. Without a properly designed landing zone, migrations create security gaps, networking issues, and governance problems that are expensive to fix later. We deploy landing zones using Terraform so every component is version-controlled, auditable, and reproducible, ensuring your cloud foundation is solid from the first workload onward.

Do you provide post-migration support?

Yes. Every migration includes 30 days of hypercare support with monitoring and incident response. After hypercare, we offer optional ongoing AWS managed services — 24/7 monitoring, cost optimization, security management, and operational support. The same team that migrated your workloads can manage them, providing continuity and deep knowledge of your environment. During hypercare, we proactively tune monitoring thresholds, optimize resource sizing based on actual production traffic patterns, and address any issues that emerge as workloads stabilize in their new AWS environment.

How do you ensure zero downtime during migration?

Our zero-downtime methodology uses continuous replication that keeps source and target synchronized in real-time while production runs normally on source systems. We test cutover procedures in advance using non-disruptive test instances, validate application functionality, and execute the actual cutover during a coordinated window — typically 15-60 minutes with immediate rollback capability. This approach means your users experience no service interruption, and your business operations continue unaffected throughout the entire migration process from first server to final cutover.

Can you migrate Windows and SQL Server workloads?

Yes. Windows Server and SQL Server migrations are among our most common engagements. Opsio handles licensing complexity including BYOL (Bring Your Own License) and License Included options, configure AWS Systems Manager for Windows management, and ensure cost optimization through AWS License Manager. SQL Server migrations use DMS with near-zero downtime. We audit all existing Windows and SQL Server licenses during assessment to identify the most cost-effective licensing strategy on AWS, frequently saving organizations tens of thousands annually in licensing costs alone.

What happens if something goes wrong during migration?

Every migration has a documented and rehearsed rollback plan. For server migrations, MGN maintains the source environment unchanged until final cutover confirmation. For database migrations, DMS continuous replication allows instant fallback to the source database. We define rollback criteria upfront, and if any threshold is breached during cutover, we execute rollback immediately without data loss. Rollback procedures are rehearsed during test migrations before the actual cutover, so the team knows exactly what to do and can execute the rollback confidently within minutes if needed.
