Migrate to AWS by using AWS Migration Hub migration tools and tracking

You can start migrating with or without first using the AWS Migration Hub discovery tools. Directly migrating servers is efficient because your servers are migrating while you simultaneously group them into applications.

Remember that if you haven't selected a Migration Hub home Region, the first time you view the console, you'll be required to select one.

It is important to understand that connecting a migration tool to Migration Hub is how you authorize that tool to communicate migration status to Migration Hub in your home Region. Without this authorization, Migration Hub will not track your migration.

As you perform the migration, the servers you are migrating appear in the Servers page. On this page you can logically define and group all the servers that comprise the applications you are migrating. You can also group more servers into either an existing or a new application at a later time. To get to the Servers page, in the Migration Hub console navigation pane, under Discover, choose Servers.

The following steps show how to use the Migration Hub to migrate your on-premises servers and application resources to AWS.

Step 1: Connect migration tools to Migration Hub

Migration happens outside AWS Migration Hub using AWS migration tools. To access these tools, in the Migration Hub console navigation pane under Migrate, choose Tools.

The table following lists the supported tools.

Resource type	Migration tool
Server	AWS Application Migration Service (Application Migration Service)–AWS Application Migration Service is the primary migration service recommended for lift-and-shift migrations to AWS. For more information about Application Migration Service, see AWS Application Migration Service and Application Migration Service Documentation.
Database	AWS Database Migration Service (AWS DMS)–For more information about AWS DMS, see AWS Database Migration Service and AWS DMS Documentation.

The preceding tools communicate directly to Migration Hub giving an aggregated view of their migrated progress and status so they can be tracked through Migration Hub.

The following steps walk you through connecting (authorizing) your selected migration tool.

To connect (authorize) a migration tool

1. In the Migration Hub console navigation pane under Migrate, choose Tools.

2. Decide upon which AWS migration tool to use to migrate your application.

3. Choose Connect in the box to authorize the migration tool you selected to communicate with Migration Hub.

   AWS migration tools utilize a one-click authorization process that automatically adds the required AWS Identity and Access Management (IAM) permissions role once you choose Connect.

Note

Note that if you are using API's or do not want to authorize through Migration Hub's console, you can learn about manual role creation in New user IAM setup for AWS Migration Hub.

Step 2: Migrate using the connected migration tools

The following steps walk you through the migration of a previously defined application.

To migrate an application

1. In the Migration Hub console navigation pane under Migrate, choose Tools.

2. After you connect (authorize) an AWS migration tool, choose the console link for the tool.

3. After you link to the tool's console, follow the migration instructions for your selected migration tool as migration happens outside of Migration Hub.

4. After your application's migration has started, return to the Migration Hub console.

Step 3: Group servers as applications

The following steps walk you through the process of grouping servers as applications when directly migrating with a migration tool without performing discovery first. (You already did this, if you first performed discovery as described in Discover on-premises resources using AWS Migration Hub discovery tools before migrating.)

After the migration tool has started, you'll see the servers listed in Migration Hub from the migration updates sent from the migration tool. You can select the servers and group them as applications. Keep in mind that the server information communicated to Migration Hub from the migration tool is not as detailed as what is collected from a discovery tool.

The following steps show you how to select the server or servers you want to group for your application, how to create your application and name it, and how to add identifying tags.

To group servers into a new or existing application

1. In the Migration Hub console navigation pane, under Discover, choose Servers.

2. In the severs list, select each of the servers that you want to group into a new or existing application.

   1. You can also search and filter on any of the criteria specified in the headers of the server list. Click inside the search bar and choose an item from the dropdown, then choose an operator from the next dropdown, and then type in your criteria.

   2. Optionally, for each selected server, you can add a descriptive tag by choosing Add tag. A dialog box appears where you can type a value for Key, and optionally, a value for Value.

3. Create your application, or add to an existing one, by choosing Group as application.

4. In the Group as application dialog box, select either Group as a new application or Add to an existing application.

   1. If you chose Group as a new application, type a name for Application name. Optionally, you can type a description for Application description.

   2. If you chose Add to an existing application, select the radio button next to the application name in the list box.

5. Choose Save. A green confirmation message appears at the top of the screen.
