Introduction;
The Data Migration Assistant (DMA) tool is a Microsoft utility designed to simplify the migration of databases from older SQL Server versions or on-premises environments to newer versions or Azure SQL Database. It helps assess compatibility, migrate schema, and transfer data. DMA also facilitates the migration of logins, ensuring users retain access to the database post-migration.
