Azure SQL migration extension for Azure Data Studio

The Azure SQL migration extension for Azure Data Studio enables you to assess, get right-sized Azure recommendations and migrate your SQL Server databases to Azure.

The key benefits of using the Azure SQL migration extension for Azure Data Studio are:

  • A responsive user interface provides you with an end-to-end migration experience that starts with a migration readiness assessment, SKU recommendation (based on performance data).
  • An enhanced assessment mechanism can evaluate SQL Server instances, identifying databases ready for migration to the different Azure SQL targets.
  • An SKU recommendation engine (Preview) that collects performance data from the source SQL Server instance on-premises, generating right-sized SKU recommendations based on your Azure SQL target.
  • A reliable Azure service powered by Azure Database Migration Service that orchestrates data movement activities to deliver a seamless migration experience.
  • The ability to run online (for migrations requiring minimal downtime) or offline (for migrations where downtime persists through the migration) migration modes to suit your business requirements.
  • The flexibility to create and configure a self-hosted integration runtime to provide your own compute for accessing the source SQL Server and backups in your on-premises environment.
