In our example, we create a BicycleStore database on SQL Server 2008 to test the downgrade. The first step is to create an empty database with the same name on the target server. Suppose we want to migrate a BicycleStore sample database that represents a simplified e-commerce system for managing bicycle products, customers, orders, and inventory to another SQL Server version. Step 1: Create an empty database on the target server These tools can be obtained either together as dbForge Compare Bundle for SQL Server or as standalone products. Let’s explore a workaround for this problem using two lightweight yet powerful tools from Devart: Schema Compare and Data Compare. Solution 1: Using dbForge Schema Compare and Data Compare This limitation also applies when attempting to attach a database from a higher version of SQL Server to a lower version. The error message is generated because SQL Server performs a version check during the restoration process, preventing the restoration of a database from a newer version of SQL Server to an older version. In our specific scenario, we backed up a database on SQL Server 2022 and tried to restore it on SQL Server 2019, which resulted in the following error message. Migrating a SQL Server database to a lower versionĮncountering errors while attempting to downgrade a SQL Server database is a common issue. In this case, the following error was shown. As a result, all operations went smoothly except for the SQL Server 2000 backup attempted to be restored on SQL Server 2012. We tried a bunch of different scenarios: tried to back up a database on SQL Server 2008 and then restored it on SQL Server 2022, backed up a database on SQL Server 2012 and tried to restore it on SQL Server 2019. Restoring a database from earlier versions of SQL Server to later versions In such cases, certain features and functionality may not be fully supported or may exhibit different behavior. Each database in SQL Server has an associated compatibility level, which can cause issues if the target SQL Server instance has another compatibility level than the database being migrated. However, being a common task, database migration between different versions of SQL Server still can present several challenges, particularly regarding compatibility levels. Feature requirements, stability concerns, testing and development needs, and migration rollbacks are additional factors that might prompt the need for a downgrade. Cost considerations may also play a role, as organizations may need to downgrade to a lower edition with reduced licensing costs. It could be caused by application compatibility issues, where an application or software solution requires a specific SQL Server version. Feature enhancements in newer versions provide advanced capabilities for data management, analytics, and reporting.ĭowngrading the version of SQL Server is not a rare thing too and may be necessary for various reasons. Newer versions, for example, often introduce performance improvements and scalability enhancements, enabling databases to handle increasing workloads more efficiently. There is a bunch of good reasons why one might need to migrate databases from older versions of SQL Server to newer ones. Migrating databases between different versions of SQL Server is a routine task undertaken by organizations seeking to stay up-to-date with the latest technology and leverage the benefits offered by newer versions.
