File Compatibility

  • Astah files are forward compatible. If files are edited by a newer version, they cannot be opened in an older version of Astah.
  • Each version of Astah has a number called “Model Version“. Every file you create with Astah will have “Model Version” which help you find which version of Astah can read this file.
