AWS Migration Hub Explained: Planning, Tracking, and Managing Cloud Migration Projects

AWS Migration Hub is the central AWS service many teams have used to discover servers, group workloads into applications, plan migration waves, and track cloud migration projects from one dashboard. If you have ever run a cutover weekend with application owners, network engineers, DBAs, and security reviewers all asking for different status views, you know why that matters.

One update you should know first. AWS documentation states that AWS Migration Hub is no longer open to new customers as of November 7, 2025. Existing customers can keep using it for ongoing migration projects. New customers are directed to AWS Transform, which AWS positions as the next-generation migration and modernization workbench with AI-driven automation and equivalent Migration Hub capabilities.

What Is AWS Migration Hub?

AWS Migration Hub gives you a single place to view discovery data, migration plans, application groupings, and migration progress across AWS migration tools. It was built for teams moving multiple applications to AWS, not just one server at a time.

In practice, Migration Hub helps you answer four questions:

• What do we have? Servers, databases, dependencies, and application groupings.
• What should move together? Application components that share traffic, data, or deployment dependencies.
• Which migration path fits? Rehost, replatform, refactor, or a mixed plan.
• Where are we now? Status across migration tools, teams, accounts, and workloads.

The service integrates with tools such as AWS Application Migration Service, also known as MGN, AWS Database Migration Service, and other AWS migration services. It also supports manual status tracking when a migration activity does not map neatly to an automated tool.

Current Availability: AWS Migration Hub and AWS Transform

If your organization already uses AWS Migration Hub, you can continue using it to finish current migration projects. AWS says existing customers will not see disruption to ongoing work.

Starting fresh? Plan around AWS Transform instead. AWS launched Transform in 2025 as a broader platform for migration, modernization, and technical debt reduction. AWS has stated that Migration Hub capabilities such as Strategy Recommendations, EC2 Instance Recommendations, Migration Hub Journeys, and Orchestrator are available in AWS Transform with improved functionality.

That shift matters. Migration is no longer treated as a one-time infrastructure move. AWS is folding migration planning into modernization, code transformation, mainframe modernization, Windows modernization, storage migration, and AI workload migration to services such as Amazon Bedrock.

How AWS Migration Hub Supports Migration Planning

Discovery and Inventory

Good migration planning starts with boring inventory work. Skip it, and you usually pay for it later during cutover.

Migration Hub works with discovery data so teams can identify servers, databases, and their relationships. You can group related infrastructure into applications, which is far more useful than looking at a flat list of hostnames. A payment application, for example, may include web servers, API nodes, a batch worker, Redis, and an Oracle database. Moving only half of that stack is how outages happen.

A practitioner detail that trips up new teams: Migration Hub uses a home Region for migration tracking and discovery data. If your discovery data appears to be missing, check the home Region before blaming the agent. I have watched teams run discovery in one Region, open the console in another, and spend an hour chasing a non-issue.

Application Grouping and Dependency Views

Migration Hub lets you organize servers and databases around applications. This helps you design migration waves. You can place tightly coupled systems in the same wave, separate low-risk workloads for early testing, and hold high-risk applications until networking, identity, backup, and security controls are proven.

This is where dependency visualization earns its keep. A single unknown TCP connection from an old reporting server to a production database can derail a cutover. Dependency data does not replace application owner interviews, but it gives you evidence when the documentation is stale. It often is.

Strategy Recommendations

Migration Hub Strategy Recommendations helps assess applications and servers at scale. It suggests migration or modernization approaches such as:

• Rehost: Move workloads with minimal change, often using AWS Application Migration Service.
• Replatform: Make limited changes, such as moving a self-managed database to Amazon RDS.
• Refactor: Redesign parts of the application for cloud-native services, containers, serverless, or managed data platforms.

To be blunt, rehost is often the right first move for deadline-driven data center exits. Refactor sounds attractive, but it can turn into expensive theater if the team has not fixed testing, observability, deployment automation, and ownership. Use Strategy Recommendations as an input, not a substitute for engineering judgment.

How AWS Migration Hub Tracks Migration Progress

The tracking function is the feature most program managers notice first. Migration Hub pulls progress from connected migration tools into a central dashboard. You can monitor server and application status instead of opening five consoles and three spreadsheets.

A typical migration flow looks like this:

1. Discover: Identify servers, databases, and dependencies.
2. Plan: Group resources into applications and define migration strategies.
3. Migrate: Use tools such as AWS Application Migration Service or AWS DMS to move workloads.
4. Track: Monitor progress until cutover and post-migration validation are complete.

For large programs, this shared view cuts status noise. Infrastructure teams see replication state. Application owners see application-level movement. Leadership sees wave progress without needing every technical detail.

Still, do not confuse tool status with business readiness. AWS DMS may show replication running, but your migration is not complete until validation, constraints, indexes, stored procedures, performance tests, and application smoke tests pass. Migration Hub is the dashboard. Your runbook is still the source of operational truth.

Managing Execution with Orchestrator and Journeys

Migration Hub Orchestrator

Migration Hub Orchestrator provides workflow templates for common migration patterns. These templates turn migration work into ordered steps, helping teams follow repeatable processes instead of improvising every time.

This is useful when you have repeated migration types, such as rehosting VMware workloads, migrating databases, or moving a standard three-tier application. Templates create consistency. They also make handoffs clearer, especially when different teams own networking, IAM, application testing, and database cutover.

Migration Hub Journeys

Migration Hub Journeys adds task pipelines and team assignment. You can build a migration journey from templates or from scratch, then assign tasks to individuals or teams. AWS ties this concept to AWS Prescriptive Guidance, so the templates reflect common migration practices.

One notable detail: Journeys can be used without an AWS account. That makes it suitable for early planning workshops, assessments, or partner-led discovery before the target AWS environment is fully established.

Automation in AWS Migration Hub

AWS introduced Migration Hub Automation to reduce repetitive migration work. It arrived in public preview in the N. Virginia Region, us-east-1, at no additional service charge, with customers paying for the underlying AWS resources and migration services they use.

The value is simple. Repeatable tasks should not live only in a spreadsheet or one engineer's memory. Automation helps standardize steps across waves and reduces manual errors. This is especially useful when paired with AWS Application Migration Service for high-volume server migrations.

Automation is not magic. You still need landing zone controls, account structure, IAM permissions, network routing, DNS plans, backup policies, and security approval paths. If those are vague, automation only helps you make the same mistake faster.

Where AWS Migration Hub Fits in Enterprise Migration Programs

AWS Migration Hub aligns well with the AWS Migration Acceleration Program, commonly known as MAP. MAP emphasizes structured assessment, mobilization, migration, and modernization phases. Migration Hub gave teams a toolset for operationalizing that approach through discovery, planning, execution workflows, and status tracking.

Common use cases include:

• Enterprise portfolio migration: Group dozens or hundreds of applications into waves and track progress centrally.
• Lift-and-shift projects: Track rehost migrations performed with AWS Application Migration Service.
• Database migration: Monitor database movement alongside application infrastructure with AWS DMS.
• Multi-team programs: Assign migration tasks across application, security, data, and platform teams.
• Modernization planning: Identify workloads that should be replatformed or refactored instead of simply copied to EC2.

AWS Migration Hub vs AWS Transform

For existing Migration Hub users, the practical question is whether to keep using it or shift planning into AWS Transform.

Use AWS Migration Hub if you are already mid-way through an active migration project and your workflows, dashboards, and teams are set up there. Stability beats novelty during cutover.

Use AWS Transform if you are starting a new migration or modernization initiative. It is where AWS is putting expanded capabilities, including AI-driven assessment, infrastructure migration across VMware, bare metal, and hybrid environments, mainframe modernization, Windows modernization, custom code transformation, and continuous technical debt remediation.

The direction is clear. Migration management is becoming portfolio transformation management. Future migration teams will need to understand not only replication and cutover, but also application modernization, code assessment, governance, data readiness, and AI workload placement.

Skills Professionals Need for AWS Migration Projects

If you are building migration expertise, get the fundamentals right before chasing advanced tooling:

• AWS account design, IAM, VPC networking, routing, DNS, and security groups.
• Migration patterns such as rehost, replatform, repurchase, retire, retain, and refactor.
• AWS Application Migration Service for server replication and cutover.
• AWS DMS for full-load and change data capture database migrations.
• Operational readiness, including monitoring, backup, incident response, and rollback planning.
• Portfolio assessment and wave planning using dependency data.

If you are building formal cloud skills, Global Tech Council's AWS, cloud computing, DevOps, cybersecurity, and data science certification paths cover the ground migration work sits on. A weak IAM model or an untested database cutover can undo months of good planning.

Best Practices for Using AWS Migration Hub Concepts

1. Set the home Region deliberately. Document it in the migration runbook.
2. Group by application, not by server owner. Business services move, not random host lists.
3. Validate dependency data with humans. Discovery tools catch traffic, but application owners know seasonal jobs and hidden batch windows.
4. Track readiness separately from replication. A replicated server is not a migrated application.
5. Automate repeatable steps only after the manual process is proven. Bad process plus automation is still bad process.
6. Plan for modernization after cutover. Rehost first if you must, but capture tech debt while the application is fresh in everyone's mind.

Final Takeaway

AWS Migration Hub gave migration teams a central way to plan, track, and manage cloud migration projects across applications, servers, databases, tools, and teams. For existing customers, it still works well for completing active projects. For new work, start with AWS Transform and treat Migration Hub concepts as the foundation: discover carefully, group applications correctly, choose the right migration path, automate repeatable work, and track business readiness as closely as technical status.

Your next step: map one real application in your environment. List its servers, databases, dependencies, owners, cutover risks, and target migration pattern. Then compare that map against AWS Transform or your current Migration Hub setup. Gaps will show up fast, and those gaps are where your migration plan needs attention.
