Copy Document Set from 2010 to 2013

Question

I copied a document set from a 2010 farm to a 2013 farm (using Explorer on both document libraries). On the destination document library, the document set was converted to a folder content type. I changed the content type to be a document set adding the information from source document library. All the metadata is attached to the folder, but it is still represented as a folder, and has no document set start page. What do I do to get the Document Set working as a document set and not as a folder? Create a document set at destination and just copying the file? Or is there something better to make this work properly?

Answer 1

Set the DocumentSet.Folder.Item.ProgId to "SharePoint.DocumentSet". Right now it will be empty. See this for more information: http://www.sharepointnadeem.com/2011/08/sharepoint-2010-document-sets.html

UPDATE Here is the sample PowerShell code. I haven't however tested it:

$web = Get-SPWeb http://yoursite
$list = $web.Lists["YourList"]
$docSetName = "YourDocSetName"
[Microsoft.SharePoint.SPFolder]$targetFolder = $web.GetFolder($list.RootFolder.ServerRelativeUrl + "/$docSetName")
if ($targetFolder.Item.ProgId -eq "")
{
    $targetFolder.Item.ProgId = "SharePoint.DocumentSet"
    $targetFolder.Item.Update()
}
