**Important**  
End of support notice: On May 20, 2026, Amazon will end support for Amazon Database Migration Service Fleet Advisor. After May 20, 2026, you will no longer be able to access the Amazon DMS Fleet Advisor console or Amazon DMS Fleet Advisor resources. For more information, see [Amazon DMS Fleet Advisor end of support](https://docs.amazonaws.cn/dms/latest/userguide/dms_fleet.advisor-end-of-support.html).

You can use DMS Fleet Advisor to discover your source on-premises databases for migration to the Amazon Web Services Cloud. Then, you can determine the right migration target in the Amazon Web Services Cloud for each of your on-premises databases. Use the following workflow to create an inventory of your source databases and generate target recommendations.

1. Create an Amazon S3 bucket, IAM policies, roles, and users. For more information, see [Creating required resources](fa-resources.md).

1. Create database users with the minimum permissions required for the DMS data collector. For more information, see [Creating database users](fa-database-users.md).

1. Create and download a data collector. For more information, see [Creating a data collector](fa-data-collectors-create.md).

1. Install the data collector in your local environment. Next, configure your data collector to make sure that it can send the collected data to DMS Fleet Advisor. For more information, see [Installing a data collector](fa-data-collectors-install.md).

1. Discover the OS and database servers in your data environment. For more information, see [Discovering OS and database servers](fa-discovery.md).

1. Collect database metadata and resource utilization metrics. For more information, see [Collecting data](fa-collecting.md).

1. Analyze your source databases and schemas. DMS Fleet Advisor runs the large-scale assessment of your databases to identify similar schemas. For more information, see [Using inventories for analysis in Amazon DMS Fleet Advisor](fa-inventory.md).

1. Generate, view, and save a local copy of the target recommendations for your source databases. For more information, see [Target recommendations](fa-recommendations.md).

After you determine the migration target for each source database, you can use DMS Schema Conversion to convert your database schemas to a new platform. Then, you can use Amazon DMS to migrate data. For more information, see [Converting database schemas using DMS Schema Conversion](CHAP_SchemaConversion.md) and [What is Amazon Database Migration Service?](Welcome.md)
