Simplify your migration with a two-step process

Better prepare your database workloads to move to Azure using the suite of Azure migration tools. First, use Azure Migrate to discover your on-premises data estate, assess migration readiness, and choose the best destination for your databases. Then, use Database Migration Service to move your on-premises databases to Azure.

Easily migrate to Azure SQL with Azure Data Studio

Migrate your SQL Server databases to Azure with the new Azure SQL Migration extension for Azure Data Studio. Using a familiar data migration software interface, expedite on-premises migrations to Azure SQL Virtual Machines and Azure SQL Managed Instance with low or zero application downtime.

Assess your SQL Server databases prior to migration

Before migrating your SQL Server databases to the cloud, use the Azure SQL Migration extension in Azure Data Studio to assess them and identify any issues that might arise during migration. The extension offers a user-friendly interface to run the assessment and generate right-sized configuration recommendations to meet your workload performance requirements.
