+# Network topologies for Azure SQL DB Managed Instance migrations using Azure Database Migration Service
+This article discusses various network topologies that Azure Database Migration Service can work with to provide a comprehensive migration experience from on-premises SQL Servers to Azure SQL Database Managed Instance.
 
 ## Azure SQL Database Managed Instance configured for Hybrid workloads 
 Use this topology if your Azure SQL Database Managed Instance is connected to your on-premises network. This approach provides the most simplified network routing and yields maximum data throughput during the migration.

 **Requirements**
-- In this scenario, the Azure SQL Database Managed Instance and the Azure Database Migration Service instance are created in the same Azure VNET, but they use different subnets.  
-- The VNET used in this scenario is also connected to the on-premises network by using either [ExpressRoute](https://docs.microsoft.com/azure/expressroute/expressroute-introduction) or [VPN](https://docs.microsoft.com/azure/vpn-gateway/vpn-gateway-about-vpngateways).

 ## Azure SQL Database Managed Instance isolated from the on-premises network
 Use this network topology if your environment requires one or more of the following scenarios:
-- The Azure SQL Database Managed Instance is isolated from on-premises connectivity, but your Azure Database Migration Service instance is connected to the on-premises network.
-- If Role Based Access Control (RBAC) policies are in place and you need to limit the users to accessing the same subscription that is hosting the Azure SQL Database Managed Instance.
-- The VNETs used for the Azure SQL Database Managed Instance and the Azure Database Migration Service are in different subscriptions.

-- Set up [VNET network peering](https://docs.microsoft.com/azure/virtual-network/virtual-network-peering-overview) between the VNET used for Azure SQL Database Managed Instance and the Azure Database Migration Service.
