# Migrating IIS applications to Elastic Beanstalk
<a name="dotnet-migrating-applications"></a>

Amazon Elastic Beanstalk provides a streamlined migration path for your Windows applications running on Internet Information Services (IIS). The migration capability described in this chapter significantly reduces the time and complexity that’s typically associated with cloud migrations, helping you to maintain application functionality and configuration integrity during the transition to Amazon.

**The **eb migrate** operation**  
Use the **eb migrate** command in the Elastic Beanstalk Command Line Interface (EB CLI), to automatically discover, package, and deploy your IIS applications to the Amazon Web Services Cloud. The process maintains application functionality and preserves your configurations, including bindings, application pools, and authentication settings.

The following steps summarize the process that the `eb migrate` operation performs to transition your application to the Amazon Web Services Cloud:

1. Discover IIS sites and their configurations.

1. Package application content and configuration.

1. Create Elastic Beanstalk environment and application.

1. Deploy the application with preserved settings.

**Workflow and location execution options**  
The **eb migrate** command provides options for flexible migration workflows and execution locations. By default, run the command on the target server that contains the application you want to migrate to Elastic Beanstalk. If you can't run commands directly on the application server, use the `remote` option to run the command from a bastion host that connects to the target server containing your application and configurations. To complete the migration in two steps, you can also generate the migration package without deploying it using the `archive-only` option and then deploy it later at your convenience using the `archive` option.

For reference information about the **eb migrate** command, see [**eb migrate**](eb3-migrate.md).
