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 Azure SQL Migration extension for Azure Data Studio offers these key benefits:
A responsive UI for an end-to-end migration experience. The extension starts with a migration readiness assessment and SKU recommendation (preview) (based on performance data).
An enhanced assessment mechanism that can evaluate SQL Server instances. The extension identifies databases that are ready to migrate to Azure SQL targets.
Note
You can use the Azure SQL Migration extension to assess SQL Server databases running on Windows or Linux.
An SKU recommendation engine that collects performance data from the on-premises source SQL Server instance and then generates 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.
You can run your migration online (for migrations that require minimal downtime) or offline (for migrations where downtime persists throughout the migration) depending on your business requirements.
You can configure a self-hosted integration runtime to use your own compute resources to access the source SQL Server instance backup files in your on-premises environment.
Provides a secure and improved user experience for migrating TDE databases and SQL/Windows logins to Azure SQL.
For information about specific migration scenarios and Azure SQL targets, see the list of tutorials in the following table:
| Migration scenario | Migration mode |
|---|---|
| SQL Server to Azure SQL Managed Instance | Online / Offline |
