Introduction
In this article, we will learn about AWS Migration Hub. Let’s start with the introduction of the AWS Migration Hub.
AWS Migration Hub (Migration Hub) allows us to discover our current servers, schedule migrations, and track the progress of each application migration in one place. The Migration Hub gives us a clear picture of our application portfolio and makes planning and tracking easier. Regardless of which migration tool we choose, we can see the connections and status of the servers and databases that make up each of the apps you're moving.

We can either start migrating right away and group servers while the migration is in progress, or we can first discover servers and then organize them into apps using Migration Hub. In any case, you may use the AWS Migration Hub to migrate each server in an application and track progress from each tool.
The following tools can provide migration status updates to Migration Hub:
AWS Application Migration Service (Application Migration Service)–For lift-and-shift migrations to AWS, AWS Application Migration Service is the primary migration service suggested.
AWS Server Migration Service (AWS SMS)
AWS Database Migration Service (AWS DMS)
Open the AWS Migration Hub console at the console.amazon and select Tools from the navigation pane under Migrate.
There are three concepts to comprehend in the Migration Hub in order to better understand how it might assist you in tracking the progress of a migration:
Applications
Availability of resources (for example, servers)
Updates
AWS Migration Hub receives updates from migration tools such as AWS AMS (AWS Application Migration Service), AWS DMS (AWS Database Migration Service) , and integrated partners' solutions. These updates provide details on how a specific resource migration (such as a server or database) progresses. An application is made up of one or more resources that have been bundled together. Each application has its own page in Migration Hub, where you can check updates for all of the application's resources.
The updates page shows when Migration Hub receives a new update. There may be a five-minute wait before the initial update appears on the updates page.
Tracking when we perform discovery first and then migrate
If we use AWS discovery tools to begin our discovery, the servers list would most likely be filled before we begin migrating. Migration Hub tries to map changes from migration tools to servers in the servers list automatically. If no match is found in the detected servers list, Migration Hub will add a server to the servers list that corresponds to the migration update and automatically map the update to the server.
Tracking when we migrate without performing discovery
If we didn't use an AWS discovery tool to find the server corresponding to the migration update, Migration Hub will automatically add it to the servers list and map the update to it. You can group servers as apps and then start tracking the migration on the details page for each application in the Migrate section of the interface.
Tagging the migration resources
Migration technologies, such as AWS Application Migration Service, report migrated resources (Amazon EC2 instances or Amazon Machine Images (AMIs)) to Migration Hub, which are automatically labeled with Application Discovery Service server IDs.
If you enable cost allocation tagging, you can use the AWS Cost Explorer Service to see the cost of the AWS resources that Migration Hub has tagged. Migration Hub's resource tagging cannot be disabled. This tagging is done automatically and does not count against your resource restriction of 50 tags.
The aws:migrationhub:source-id tag is present on these pages, and the source-id matches the server.
Application Discovery Service's configurationId server asset field.
Choosing a Migration Hub home Region
Select a Migration Hub home Region when you first use the AWS Migration Hub console. You'll be required to choose a home Region before you can execute any write actions from the console, SDK, or CLI if you haven't already. You are instantly taken to the console in that AWS Region after selecting a home Region.
We may select and examine our current home region on the AWS Migration Hub Settings page. Choose Settings from the left navigation to get to the Settings page.
Whether we're transferring apps into one AWS Region or ten, the Migration Hub console in our home Region gives us detailed visibility into discovery and migration.
Navigating from the dashboard and the navigation pane
You might want to get more detail after viewing dashboard data summaries without interrupting your workflow. This is accomplished by directly navigating from the relevant status or information pane on the dashboard.
Instructions for navigating from a dashboard to the information you want to see are provided in the table below. The navigation pane also contains instructions on how to access this information.
