Once the MSDE 2000 installation installs Service Pack 4, that instance can be upgraded, in-place, to SQL Server 2008 R2 Express with Service Pack 1. To perform the upgrade, follow the instructions below:
- Run the SQL Server 2008 R2 Express installer
- Click Installation in the SQL Server 2008 R2 Installation Center, then click Upgrade from SQL Server 2000, SQL Server 2005 or SQL Server 2008
- Select the MSSQLSERVER instance to upgrade (if it is not already selected)
During the upgrade process, the following error message may appear when the installer tries to connect to the SQL Server instance while the server is running in single-user mode:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
The above error can safely be dismissed by clicking Cancel.
If the above error does come up, a Windows Error Reporting dialog may appear once the SQL Server upgrade process has completed. Dismiss the Error Reporting dialog and verify that the upgrade process completed successfully.
Once the upgrade process has completed, verify that the GlasPacLX application can connect to the GlasPacLX database and that the application functions normally. The upgrade process removes the MSDE services and application from the computer.
