在Orchard CMS中导入/导出配方

Question

每当我尝试导入更改时，我都遇到了很多问题。 我们为不同的环境提供了三个果园实例。在一个中进行的更改应迁移到剩余的两个实例。为此，我在orchard CMS（v 1.6.0.0）中使用导入/导出模块。

导出文件仅包含我在CMS1中所做的更改=＆gt; CMS1.xml和已经存在的CMS1.xml将从文件中删除。如果我更新资源文本，即。，＆＃34; Export Untouched＆＃34; to＆＃34; Export Modified＆＃34;并保存对XML文件的更改，然后当我将此文件导入CMS2和CMS3实例时，这些导入无效。

注意：我没有更改密钥，我只更新了值。

例外：
