Troubleshooting AWS Migration Hub

Following, you can find information on how to troubleshoot issues for AWS Migration Hub.

My Migrations Do Not Appear in Migration Hub

If you are not seeing your applications' migration status updates on the Updates page in Migration Hub, it could be due to one of the following reasons:

  • You have not selected a home region or you are not currently viewing the home region console.

  • Migration tools are not authorized to communicate with Migration Hub.

  • You do not have the necessary policies and roles set up in IAM.

  • Migration status mapping is incorrect or needs to be done manually.

Authentication

To make sure authentication is occurring correctly:

Migration Status Matching When Using AWS Discovery Tools

  • Check whether a migration update must be manually mapped or was incorrectly mapped to a discovered serve., See Tracking Migration Updates.

Updates About My Migrations Don't Appear Inside an Application

If you are not seeing your migration updates associated with an application, it could be due to one of the following reasons:

  • Servers not being grouped as an application.

  • Migration update status not being refreshed.

  • Migration updates are not mapped or are incorrectly mapped to a server.

Servers' Application Grouping

Update Status

Update and Server Mapping

  • Check whether the update is present on Updates page.

  • If not on the Updates page, then check whether the migration tool was authorized by looking on the Migration Tools page - in the navigation pane, under Migrate, choose Tools.

  • On the Updates page, verify that the update is mapped to the correct server (it will show "Edit" in "Mapped servers" column).

  • If mapped to a server on the Updates page, then verify whether the server is grouped into an application on the Servers page with an application name present in the "Applications" column.

My API Call Failed

  • Check whether you called GetHomeRegion before your call, if required.

  • You can use the AWS Migration Hub home region APIs within your home region only. API calls originating from outside your home region are rejected, except for the ability to register your agents and connectors.

Errors Enabling Data Collection

Although you can register discovery agents and connectors outside of your AWS Migration Hub home region, you cannot start data collection outside the home region. The Application Discovery Service StartDataCollection API call prevents you from enabling data collection outside the home region.
