To start discovery and planning, you can deploy data collectors, such as AWS Application Discovery Agent (Discovery Agent) or Application Discovery Service Agentless Collector (Agentless Collector), into your data centers. These tools send data to the AWS Migration Hub service in your home Region, and the information is displayed in your home Region in the console.
Before you install your data collectors, you must choose an AWS Migration Hub home Region as described in Choose an AWS Migration Hub home Region. Before collecting data, you must register your collectors in your home Region. If you're using the AWS CLI, you must set up your AWS CLI to use the home Region as the default Region.
Discovery Agent discovers data for many types of hardware, hypervisors, and operating systems including Linux and Windows. An agent must be installed on each host that is targeted for migration. For specific information about the data fields that are returned by Discovery Agent, see Data collected by Discovery Agent in the Application Discovery Service User Guide.
Agentless Collector discovers data for VMware vCenter hosts and systems, using VMware metadata. For specific information about the data fields that are returned by Agentless Collector, see Data collected by Agentless Collector in the Application Discovery Service User Guide.
Alternatively, you can use Migration Hub import to import details of your on-premises environment directly into Migration Hub without using Agentless Collector or Discovery Agent. For more information, see Migration Hub import.
