This section guides you through the steps you must take to configure your operating system and database servers. Then, you'll discover your servers and have the option to add a database or analytics server manually. 

For database discovery, you must create users for your source databases with the minimum permissions required for the data collection module. For more information, see [Creating database users for AWS DMS Fleet Advisor](https://docs.aws.amazon.com/dms/latest/userguide/fa-database-users.html) in the *AWS DMS User Guide*.
