Upgrading Microsoft SQL Server
Before upgrading to Windchill Modeler 9.4, ensure that you upgrade your SQL Server from 2014 or 2016 (or any older version) to a supported version as Windchill Modeler 9.4 does not support SQL Server versions 2016 or older. This topic explains how to upgrade your SQL Server.
