SharePoint 2013 Powershell - 将文件从一个网站集复制到另一个
SharePoint 2013 Powershell - Copy File From One Site Collection To Another
有人可以协助解决上述问题吗？
我想将一个文件从 Sharepoint 网站集中的特定文件夹复制到另一个 Sharepoint 网站集中（但仍在同一 Web 应用程序中）的另一个库（同名）。
我的 Powershell 经验很少，并且尝试了多次 Google 搜索，但似乎找不到任何有用的东西。
下面是我尝试做的事情的一个例子（大量的 Write-Host 试图弄清楚发生了什么），底部有错误消息。

所以对于文件大小大于 50MB 的大文件。 @LZ_MSFT 提到的这个脚本可能永远无法复制该文件。在这方面，您需要将文件分块成小 pieces.Here 是 PS 如果文件大小大于 50MB，则使用分块从源复制到目标。这个脚本的优点是，它使用客户端，因此它可以与 SP 在线和 on-prem.
