The Access Group develops and tests any future product releases on currently supported mainstream versions of both Microsoft OS® and Microsoft SQL Server®.
We cannot guarantee that non mainstream supported Microsoft SQL® versions will not have issues, although the product framework is built to be backward compatible.
Our recommendation if you are currently using Microsoft SQL Server 2017® as a minimum. If you are planning to upgrade for your business, we would suggest opting for a higher version for the optimum support term.
See Microsoft® SQL Server® Lifecycle for details and support end dates.
Mainstream support includes functional, performance, scalability, and security updates.
Extended support includes only security updates
End of support (also sometimes known as end of life) indicates that a product has reached the end of its lifecycle, and servicing and support are no longer available for the product.
Once your SQL Server® has reached the end of support stage:
Upgrade to a current version of SQL Server®.
