Amazon Web Services
AWS Migration Services
Move servers, databases and applications to Amazon Web Services in planned waves, backed by data-driven assessments, a secure landing zone and rehearsed cutovers.
Migrate to AWS with a Plan You Can Trust
AWS has reshaped its migration tooling around AWS Transform, an agentic service that brings together assessment, wave planning and execution, with AWS Transform MGN (formerly AWS Application Migration Service) as the replication engine for rehosting. AWS Database Migration Service and DMS Schema Conversion handle database moves. These tools speed up the mechanics, but the decisions that determine success remain human: which applications to move first, which to modernize, and how to cut over without disrupting the business.
Hanoi Technology combines AWS tooling with structured discovery, application owner interviews and a landing zone built before the first wave. We migrate in repeatable waves and validate each workload for performance, security and cost before decommissioning the source.
The Challenge
Where AWS Migrations Run into Trouble
Migration risk concentrates in planning gaps rather than in the replication itself.
Unreliable Inventory
Outdated CMDB data and undocumented integrations lead to missing servers in wave plans and surprises after cutover.
Business Case Uncertainty
Estimates based on on-premises specifications rather than measured utilization produce oversized instances and inflated cost forecasts.
Foundations Built Too Late
Migrating into accounts without guardrails, networking standards or centralized logging creates security findings that halt later waves.
Cutover and Rollback Risk
Without rehearsed runbooks, data synchronization plans and rollback criteria, business owners resist approving migration windows.
Business Value
What a Structured AWS Migration Delivers
Right-Sized Infrastructure
Assessments based on real utilization data recommend EC2 instance types, including Graviton options where applications support them, matched to actual demand.
Minimal Downtime Cutovers
Continuous block-level replication with AWS Transform MGN keeps targets current, so cutovers only need a short final synchronization.
Reduced Operational Burden
Moving databases to Amazon RDS or Aurora removes patching, backup and failover management from your team’s workload.
A Base for Modernization
Once workloads run on AWS, containerization, serverless and data platform modernization become incremental steps.
Speed Comes from Repetition
The fastest migrations run like a factory: one landing zone, standard runbooks, clear decisions per application and a steady cadence of waves. Each wave is faster and lower-risk than the previous one because the team has practiced every step.

Use Cases
AWS Migration Scenarios
Typical migrations we plan and execute.
VMware Exit
An organization facing virtualization license renewal migrates VMware workloads to Amazon EC2 using AWS Transform, with network configurations translated into AWS VPC designs.
Oracle to Aurora PostgreSQL
An Oracle database is converted with DMS Schema Conversion and migrated to Aurora PostgreSQL, removing proprietary database license costs.
SQL Server to Amazon RDS
SQL Server instances move to Amazon RDS for SQL Server, gaining automated backups, patching and Multi-AZ high availability.
Windows Application Modernization
Legacy .NET Framework applications are analyzed and ported to modern .NET to run on Linux containers.
Cloud-to-Cloud Migration
Workloads from another cloud provider are replicated to AWS with AWS Transform MGN and consolidated into the AWS landing zone.
Acquisition Integration
An acquired company’s servers and databases are migrated into the parent organization’s AWS Organization with aligned guardrails.

AWS Migration FAQ
What is AWS Transform and how does it relate to MGN?
AWS Transform is AWS’s agentic migration and modernization service, launched in 2025, which covers assessments, migrations including VMware, Windows and .NET modernization, mainframe modernization and custom code transformation. In June 2026 AWS renamed AWS Application Migration Service to AWS Transform MGN, reflecting its role as the replication engine. You can rehost through the agentic workflow or directly in the MGN console. AWS Migration Hub stopped accepting new customers in November 2025.
How long does an AWS migration take?
Assessment and planning usually take a few weeks, and a landing zone can be built in parallel. Pilot waves follow, then regular waves often every two to four weeks. The total duration depends on the number of applications, their interdependencies and how much modernization you combine with the move. We publish a full wave plan early so business owners can schedule around peak periods and change freezes.
How do you keep downtime low?
Servers replicate continuously before cutover, so only recent changes need to be synchronized during the final switch. Databases use full load plus change data capture with AWS DMS where supported. We perform test launches, rehearse runbooks and agree cutover windows and rollback criteria with business owners. Hypercare follows each cutover so any issues are resolved quickly by the people who performed the migration.
What does an AWS migration cost?
There are two cost elements: the migration effort and future AWS consumption. Effort depends on workload count, complexity, testing and compliance needs. Consumption depends on instance sizing, storage, licensing and commitments. We estimate both before migration starts, using assessment data and the AWS Pricing Calculator, and identify savings options such as Graviton instances, Savings Plans and moving databases off commercial licenses.
How do you handle security during migration?
Security is part of the landing zone before any workload moves: account separation, service control policies, IAM Identity Center, encryption with AWS KMS, centralized CloudTrail logging, AWS Security Hub and Amazon GuardDuty. Replication traffic is encrypted in transit. Each wave includes a security review, and workloads do not go live until they meet the agreed baseline.
Should we modernize while we migrate?
Combining a deadline-driven data center exit with large-scale refactoring often delays both. A common approach is to rehost most workloads first, then modernize selected applications where the benefits are clear, such as databases moving to Aurora or applications moving to containers. Some low-effort replatforming, like moving databases to Amazon RDS, can be included in the initial migration without much additional risk.
