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 SmartPlant Engineering Upgrade Utility, you can use the Upgrade Reference Data command in SmartPlant P&ID Options Manager to upgrade styles, template files, symbols, and assemblies.
Before you can upgrade the reference data and drawings for an upgraded plant, you must define user access for the plant in SmartPlant Engineering Manager. For more information about defining user access, see the SmartPlant Engineering Manager User's Guide.
After you upgrade reference data, you cannot view it in earlier versions of the software.
For information about changes made during the reference data upgrade, see the V4RefDataUpgrade.log file. This log file is saved in the folder where the symbols are stored. For more information about upgrading reference data, see the SmartPlant P&ID Options Manager User's Guide.
