What is SQL Server data migration?

SQL Server data migration is the process of transferring data from one SQL Server database to another, or from a different database system into SQL Server. This process may involve moving data, schema, and objects such as tables and stored procedures. Data migration is commonly performed during system upgrades, consolidations, or when moving to new hardware or cloud environments. It requires careful planning to minimize downtime and ensure data integrity and security. Tools like SQL Server Integration Services (SSIS), Data Migration Assistant (DMA), and Azure Database Migration Service are often used to facilitate the process.
