Before you upgrade AutoCAD, update Design Master to the latest version. Make sure Design Master has updated successfully, then upgrade AutoCAD.
When you first run the new version of AutoCAD, it will ask if you want to migrate your settings from your previous version. If you say Yes, the Design Master menus will be transferred automatically. Depending upon the AutoCAD version, it may be necessary to load a different Design Master menu. The new menu will automatically be loaded for you.
If you say No to transferring your settings, you will need to load the Design Master menus in the new version of AutoCAD. Visit the Design Master installation page for a single-user installation or multiple-user installation and follow the instructions under Configure AutoCAD.
