23 Jul, 2025
Migrating databases from SQLite to SQL Server can be a complex but necessary process for organizations aiming to scale operations by improving performance or leveraging advanced database features. SQLite is favored for its lightweight design, whereas SQL Server offers robust capabilities ideal for enterprise-level applications.
In this article, We will learn about How to migrate SQLite to SQL Server by understanding the step-by-step processes and so on.
How to Migrate SQLite to SQL Server
- Migrating databases can be a challenging task, but it's often necessary to scale operations, enhance performance or utilize advanced features offered by different database systems.
- SQLite is widely used for its lightweight nature, whereas SQL Server provides robust capabilities suitable for enterprise-level applications.
- We will discuss a systematic approach to seamlessly migrate our SQLite database to SQL Server.
Migrate from SQLite to SQL Server
Step 1: Downloading an ODBC Driver for SQLite
1. Download the SQLite Driver-To begin the migration process, download the SQLite ODBC driver. This driver acts as a bridge, allowing SQL Server to communicate with the SQLite database. Visit the official SQLite website or another trusted source to download the appropriate ODBC driver for your operating system. Ensure you choose the version compatible with your system architecture (32-bit or 64-bit).
Step 2: Installing the Driver
2. Open SQLite 3-Once you have the driver, open SQLite 3, the command-line interface or graphical user interface for managing SQLite databases. If you don't have SQLite 3 installed, download it from the official SQLite website and follow the installation instructions.
3. Create or Open a Database-In SQLite 3, create a new database or open an existing one that you intend to migrate. To create a new database, enter the command `sqlite3 database_name.db` in the SQLite 3 interface, where `database_name.db` is the name of your new database file.
Step 3: Creating a System DSN for the Database
4. Access the Run Command-Press the Windows key + R on your keyboard to open the Run command box. This allows you to quickly execute commands and open various Windows settings.
5. Open ODBC Data Source Administrator-In the Run command box, type `odbcad32` and press Enter. This command opens the ODBC Data Source Administrator, a utility that manages database connections through ODBC drivers on your system.
6. Configure System DSN-In the ODBC Data Source Administrator window, navigate to the "System DSN" tab. System DSN (Data Source Name) configurations are available to all users on the computer and ensure that the SQLite database connection is accessible system-wide.
7. Add a New Data Source-Click the "Add" button to create a new data source. From the list of available ODBC drivers, select "SQLite3 ODBC Driver" and click "Finish." If the SQLite ODBC driver is not listed, ensure it was installed correctly.
8. Configure the Data Source-In the configuration window, enter a meaningful name for your new data source in the "Data Source Name" field. This name will be used to identify the connection. Click the "Browse" button to locate and select the SQLite database file you created earlier.
9. Complete the Data Source Setup-After selecting the SQLite database file, click "Open" to confirm your choice. Then click "OK" to save the data source configuration. At this point, your SQLite database is ready to be connected to SQL Server via the ODBC driver.
Step 4: Creating a Linked Server in SQL Server
10. Create a New SQL Linked Server-Open SQL Server Management Studio (SSMS) and connect to your SQL Server instance. In the Object Explorer, right-click on "Linked Servers" under the "Server Objects" node, and select "New Linked Server." This action opens a dialog to configure a new linked server.
11. Select Other Data Source-In the "New Linked Server" dialog, under the "General" tab, select "Other data source." This option allows you to specify a non-SQL Server data source to link with your SQL Server instance.
12. Choose Microsoft OLEDB Provider for ODBC Drivers-In the "Provider" dropdown menu, choose "Microsoft OLE DB Provider for ODBC Drivers." This provider allows SQL Server to communicate with various ODBC data sources, including the SQLite database you set up earlier.
13. Configure the Linked Server-In the "Product Name" field, you can enter "SQLite" or any descriptive name. In the "Data Source" field, enter the Data Source Name (DSN) you created in the ODBC Data Source Administrator. This links the SQL Server instance to your SQLite database.
14. Finalize the Linked Server Setup-Click "OK" to save the linked server configuration. Your SQL Server is now linked to your SQLite database, and you can start querying and migrating data from SQLite to SQL Server using SQL Server Management Studio.
Step 5: Selecting the Data from the Source and Inserting it into SQL Server Database Table
15.Select and Insert Data-With the linked server set up, you can now select data from your SQLite database and insert it into your SQL Server database tables. Use SQL Server Management Studio to write and execute the necessary queries to transfer the data.
Conclusion
Migrating from SQLite to SQL Server involves several steps but is a manageable process with the right guidance. By following this detailed guide, you can ensure a successful migration, allowing you to leverage the powerful features of SQL Server for your applications. This process not only facilitates data transfer but also sets the foundation for future scalability and performance enhancements.
