SharePoint 2013: Copying Pages between Wiki Page Libraries using PowerShell

July 15, 2016

Baris Bikmaz has a good Blog Post on Move a SharePoint Team Wiki Library between SharePoint Sites or Site Collections in SharePoint 2010. There is no good method in SharePoint 2013 to copy pages between Wiki Libraries. Using SharePoint Designer, SharePoint Template Library, or using Export-SPWeb PowerShell command does not produce desired results. The Home.aspx page is not a default page.

Using Explorer view and copying files between the libraries keeps the Home.aspx page as a default page but fails to copy the pages’ content.

PowerShell to the rescue. The following script will copy document from one Wiki Library to another in SharePoint 2013. It assumes both source and destination libraries exist in the same SharePoint Farm. You can create destination Wiki library by navigating to Site Settings / add an app and selecting Wiki Page Library

        }
        Write-Host -foregroundcolor green ('Success!!!')
    }
    catch [System.Exception] {
       Write-Host 'Error while copying Wiki page: ' -foregroundcolor red  -NoNewline
       $Error[0]
    }
 }

If you need to migrate Wiki Page Libraries between the farms you will need to use CSOM

 

Happy Scripting!
