To upgrade SQL Server 2008, follow these steps: 1. **Access the R2 Install Center**: Open SQL Server Management Studio (SSMS) and navigate to the **Database Administration** tab, then select **Server Setup** and choose **R2**. 2. **Choose Version Upgrade**: In the R2 Install Center, select **Version Upgrade**. Restart the computer if prompted during the process. 3. **Input Activation Key**: After the installation completes, input the appropriate activation key: - **SQL Server 2008 Developer**: PTTFM-X467G-P7RH2-3Q6CG-4DMYB - **SQL Server 2008 Enterprise**: JD8Y6-HQG69-P9H84-XDTPG-34MBB 4. **Upgrade Process**: Continue the upgrade until it requires entering the activation key. If the upgrade fails, check the SQL Server Service and ensure it's enabled. If issues persist, modify the `CommonFiles` value in the SQL Server's configuration: - Open the Run dialog and type `regedit`. - Navigate to `HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server100ConfigurationState` and set `CommonFiles` to 3. 5. **Reinstall and Retry**: After modifying the configuration, exit and restart SQL Server. Attempt the **Version Upgrade** again, this time selecting **Only Upgrade Shared Features**, as the database has already been upgraded.
