尝试使用OrientDB's export/import functionality，但是我一直在从命令行客户端和使用JavaAPI获取错误
使用最少的内容创建数据库，然后调用
export database /tmp/db.export -excludeAll -includeClass="asdf"
然后用
导入import database /tmp/db.export.gz
产生错误消息Invalid format. Found unsupported tag 'brokenRids'。以下是重现的完整控制台会话：

任何帮助都非常感激。
编辑：导出的数据如下所示：
gunzip -c /tmp/test_export_import.export.gz
{"records":[{"@type":"d","@rid":"#17:0","@version":1,"@class":"asdf","one":"two","three":"four"}],"brokenRids":[]}
答案 0 :(得分：0)
这意味着您尝试导入由旧版ODB导出的数据。我们不支持从未来版本到过去版本的兼容性，但当然也支持相反的兼容性。
