The [Azure SQL Migration extension for Azure Data Studio](/sql/azure-data-studio/extensions/azure-sql-migration-extension) enables you to assess, get Azure recommendations and migrate your SQL Server databases to Azure.
1919

20+
The key benefits of using the Azure SQL Migration extension for Azure Data Studio are:
21+
1. Assess your SQL Server databases for Azure readiness or to identify any migration blockers before migrating them to Azure. You can assess SQL Server databases running on both Windows and Linux Operating System using the Azure SQL Migration extension.
22+
1. Get right-sized Azure recommendation based on performance data collected from your source SQL Server databases. To learn more, see [Get right-sized Azure recommendation for your on-premises SQL Server database(s)](ads-sku-recommend.md).
23+
1. Perform online (minimal downtime) and offline database migrations using an easy-to-use wizard. To see step-by-step tutorial, see sample [Tutorial: Migrate SQL Server to an Azure SQL Managed Instance online using Azure Data Studio with DMS](tutorial-sql-server-managed-instance-online-ads.md).
24+
1. Monitor all migrations started in Azure Data Studio from the Azure portal. To learn more, see [Monitor database migration progress from the Azure portal](#monitor-database-migration-progress-from-the-azure-portal).
25+
1. Leverage the capabilities of the Azure SQL Migration extension to assess and migrate databases at scale using automation with Azure PowerShell and Azure CLI. To learn more, see [Migrate databases at scale using automation](migration-dms-powershell-cli.md).

- We recommend up to 10 concurrent database migrations per self-hosted integration runtime on a single machine. To increase the number of concurrent database migrations, scale out self-hosted runtime up to four nodes or create separate self-hosted integration runtime on different machines.

- Configure self-hosted integration runtime to auto-update to automatically apply any new features, bug fixes, and enhancements that are released. To learn more, see [Self-hosted Integration Runtime Auto-update](../data-factory/self-hosted-integration-runtime-auto-update.md).

## Pricing
116130
- Azure Database Migration Service is free to use with the Azure SQL Migration extension in Azure Data Studio. You can migrate multiple SQL Server databases using the Azure Database Migration Service at no charge for using the service or the Azure SQL Migration extension.
117131
- There's no data movement or data ingress cost for migrating your databases from on-premises to Azure. If the source database is moved from another region or an Azure VM, you may incur [bandwidth charges](https://azure.microsoft.com/pricing/details/bandwidth/) based on your bandwidth provider and routing scenario.
118132
- Provide your own machine or on-premises server to install Azure Data Studio.
119133
- A self-hosted integration runtime is needed to access database backups from your on-premises network share.
