You can use different migration methods to move your data between SQL Server, Azure SQL Database, and Azure SQL Managed Instance. Some methods are **Online** and picking-up all changes that are made on the source while you're running migration, while in **Offline** methods you need to stop your workload that is modifying data on the source while the migration is in progress.

Azure SQL Managed Instance is a PaaS service that has near 100% compatibility with the latest Enterprise Edition SQL Server Database Engine. It provides a native [virtual network (VNet)](/azure/virtual-network/virtual-networks-overview) implementation that addresses common security concerns, and a [business model](https://azure.microsoft.com/pricing/details/sql-database/) favorable to existing SQL Server customers. SQL Managed Instance enables existing SQL Server customers to lift and shift their on-premises applications to the cloud with minimal application and database changes. At the same time, SQL Managed Instance provides all PaaS capabilities (automatic patching and version updates, [automated backups](automated-backups-overview.md), [high availability](high-availability-sla-local-zone-redundancy.md)) to drastically reduce management overhead and the total cost of ownership (TCO).

SQL Managed Instance is designed for customers who want to migrate a large number of apps from an on-premises or IaaS, self-built, or ISV provided environment to a fully managed PaaS cloud environment, with as low a migration effort as possible. By using the fully automated [Azure Data Migration Service](/azure/dms/tutorial-sql-server-to-managed-instance#create-an-azure-database-migration-service-instance), or the [Managed Instance link](managed-instance-link-feature-overview.md), customers can lift and shift their existing SQL Server database or SQL Server instance to Azure SQL Managed Instance, which offers compatibility with SQL Server and complete isolation of customer instances with native VNet support.

With Software Assurance, you can allocate your existing licenses for discounted rates on SQL Managed Instance by using the [Azure Hybrid Benefit for SQL Server](https://azure.microsoft.com/pricing/hybrid-benefit/). SQL Managed Instance is the best migration destination in the cloud for SQL Server instances that require high security and a rich programmability surface.
