An unsupported SQL Server version is a version of SQL Server that is no longer receiving security updates or bug fixes from Microsoft. This can make your SQL Server installation vulnerable to security attacks and other problems. Microsoft recommends that you upgrade to a supported version of SQL Server as soon as possible.
Here are some of the risks of running an unsupported SQL Server version:
- Security vulnerabilities: Unsupported SQL Server versions are more likely to contain security vulnerabilities that can be exploited by attackers. These vulnerabilities could allow attackers to take control of your server, steal your data, or even launch a ransomware attack.
- Performance issues: Unsupported SQL Server versions may not have the latest performance optimizations and bug fixes, which could slow down your applications.
- Compatibility problems: Unsupported SQL Server versions may not be compatible with the latest versions of Windows and other software products. This could cause problems with your applications or even make them unusable.
To upgrade to a supported version of SQL Server, you can use the SQL Server Upgrade Assistant. This tool will help you identify any potential compatibility issues and guide you through the upgrade process.
Here is a table of the currently supported SQL Server versions:
| Version | Support End Date |
|---|---|
| SQL Server 2022 | October 14, 2028 |
| SQL Server 2019 | July 9, 2024 |
| SQL Server 2017 | July 12, 2022 |
| SQL Server 2016 | July 10, 2021 |
If you are running an unsupported version of SQL Server, I recommend that you upgrade to a supported version as soon as possible. This will help to protect your data and applications from security risks and other problems.
