Microsoft SQL Server is the most widely used database management system to store and maintain data, information. With the advancement of online storage platforms, we have cloud storage servers for SQL data like Azure SQL and Amazon RDS. The most popular alternative to on-premises SQL Server is Azure SQL to which many SQL users are already migrating from their on-premises environments. Mostly these migrations are performed using manual ways or using migration tools.
Talking about the manual ways of migration, a combination of two manual utilities can help to move SQL database to Azure SQL cloud. We are going to explain this manual way for migration in detail.
Data Migration Assistant is an in-built tool provided by Microsoft to help in migrating on-premises SQL Server database to the Azure SQL Server destination. It assesses database compatibility issues and feature parity in the target.
Let us move ahead with this pre-assessment via Data Migration Assistant tool.
Download the Data Migration Assistant utility on your system first, and then install it. Now, start this tool, go to New +>>Assessment project type. In Source server type, add a project name and choose SQL Server. In Target server type, choose Azure SQL Server Database as your database server type and finally click Create.
Two reports – Check database compatibility and Check feature parity are by default selected, click Next to move further. Then provide your source server details and database name to connect it. Finally start the assessment by clicking Start Assessment. The assessments includes set of recommendations helping to plan the migration projects, compatibility issues which could block the migration in between along with suggestions to deal with it. Once assessed and resolved all the issues (if there), we can move ahead with the actual migration.
Now, the migration of on-premises SQL database to Azure SQL Server goes through 3 stages.
Please carry out the following set of instructions to migrate SQL Server schema to Azure database.

Users can use the Azure portal interface to register resource provider (Microsoft.DataMigration) to the target server.
Before creating a migration project, you need to create an instance in the Azure portal. For that, search
Azure Database Migration Service and click on it. Then click Create on the Azure Database Migration Service page.
Next provide details like Service Name, Subscription, resource group, Location, Pricing tier, etc. Then click on Create to start the service.
Once it is created, search for it in the Azure portal and open it. Then select the instance that you have just created.
This was the whole procedure to move SQL database to cloud (Azure SQL) manually with the help of utilities provided by Microsoft – Data Migration Assistant and Microsoft Data Migration Service.
Drawbacks – After we explained the whole manual process above for the migration, we should also mention some drawbacks. The above method seems quite technical, lengthy to perform and have chances of manual errors which might lead to incomplete or flawed migration.
If you do not feel comfortable with the manual ways to migrate your on-premises SQL Server data to Azure SQL Server, then choose the most efficient automated tool – the Kernel Migrator for SQL Server. It can transfer or migrate your MDF or LDF files data directly to Azure SQL.
The tool also allows users to move SQL Server to Amazon RDS destination. It provides previews of SQL database objects before the migration. So, this professional way to move SQL database to cloud is far easy and efficient than the manual one.
The blog provides all the details related to manual migration of SQL Server to Azure SQL along with mentioning its drawbacks. To ease the migration, it mentions the use of a trusted SQL Migration tool as well.
This is an incredible tool that moved SQL DB to Azure SQL without any data loss
