使用内容部署API，当文档不是时，ListItem重复了

Question

我正在制作一种工具，将特定内容（列表项目和文档）从农场迁移/更新到另一个。有点像 SharePoint内容部署向导, ，但具有我客户的自定义规格。

使用内容部署API似乎很好 主意.

每个农场中的站点收集都是使用标准过程（使用自定义站点定义供应列表和ELT）创建的。我认为我不应该使用”保留对象“因为两个农场之间的GUID不同。

当我导出/导入数据时：

• 文档已正确添加/更新，但列表项目并非如此：
• 它不会更新现有列表项目。它总是添加新的。

因此，这是我的问题：更新现有列表项目的最佳解决方案是什么（它们之间没有相同的指导）？我想保留ListItem.ID（不是唯一的）。那可能吗 ？是否有解决方案告诉API将此项目还原到该项目？在最坏的情况下，我可以在导入之前删除现有项目，但是这些项目将失去其原始的ListItem.ID（INT）...

或者我可以忘记内容部署API ...

                SPExport export = new SPExport(settings);
                export.Run();

我找到了一个解决方案：

微软让我们修改 XML文件 用于导入数据：

所以我做了什么：

• 将导入设置设置为true。
• 修改XML文件以更改现有内容的指南

现在，有很多硬编码的东西，但是我认为，我将能够使其更通用。

顺便说一句，我不知道我是否应该编辑我的问题

原因是SharePoint API本身处理版本的方式。当您启用使用重复的文件名和版本控制调用SPFOLDER.ADD（）时，添加了新版本（而不是添加了新文件）。

您可能想尝试的一件事是在导入之前启用列表上的版本控制 - 这可能允许更新（保存版本）。

如果不是，恐怕您已经确定，唯一的方法是在运行导入之前清除列表。
