我已成功将magento 1.4.1数据库升级到1.4.2，然后又升级到1.6.0。我还能够成功地将 1.6.0数据库中的data 设置和迁移到Magento 2.1.2数据库中。（情况看起来很棒！...）
从那以后，我一直在2.1.2站点上工作；添加新主题，更改某些设置以及编辑cms块。我所做的所有这些假设都是我可以运行一个migration：delta并带来新的客户和订单数据，因为这是启动新站点真正需要的。（我没有在2.1.2数据库中创建任何新订单或客户）
在尝试迁移：delta（在我再次执行1.4.1-> 1.6.0升级过程以获取当前的实时数据之后）时，我遇到了缺少deltalog表（前缀为m2cl *）的错误。我从迁移的第一个数据库中提取了全部为空的那些表。这使我可以运行带有以下警告的migration：delta：

- 我采取的正确方法是从1.4.1到2.1.2获取数据的方法吗？
- 是否有丢失的引用的迁移：三角洲正在寻找
，因为这个更新的数据库是不是原单，我从迁移？ - 还有标题问题
