Reference data often changes between versions of the software. These changes can include deletions and additions to reference data, as well as modifications to existing data formats and locations.
After you upgrade your plant data using the Smart Engineering Manager Upgrade Utility, you can use the Upgrade Reference Data Command to automatically change the reference data to the correct information based on the plant and database settings that were entered when your plant was created and on the requirements for the new reference data.
Any changes made to the symbology in the Icon layer is updated in the reference data when you upgrade the reference data, allowing the Catalog Explorer to load the updated images for accurate information.
Before you can upgrade the reference data and drawings for an upgraded plant, you
must define user access for the plant in Smart Engineering Manager. See the Smart Engineering Manager Help.
