Can an XML model file from an earlier version of Data Modeler be opened in a newer version?
Answer: Not directly. The XML model metadata changes each release and is not directly compatible with newer releases. Instead it is recommended that the XML be opened in the older release first and saved as a .erwin file. Data Modeler will then automatically upgrade the .erwin file when opened in a newer release and can be re-saved as XML as needed. For more information on saving files as XML, please see here:
