Upgrading is the process of converting an existing model, with all its associated files and databases, from compatibility with an older release to compatibility with the next sequential release of the software. The databases you must upgrade include the Site, Site schema, Catalog, Catalog schema and Model databases. The associated files you must upgrade are those that are located in the SharedContent (Symbols) share. This set of databases (plus the Reports and Reports schema databases) and files are collectively referred to as the Smart 3D configuration.
