I have an old sharepoint site containing around 50 document libraries with subfolders and files. No these document libraries should be moved to a new SharePoint 2010 site.
I've tried this using the copy and paste within the explorer viewer of both sites. But this does not work perfectly. Some subfolders are not copied for some reason. Also, if I paste the folders in the root of the SharePoint 2010 site, the document library does not show up when I browse to SharePoint site with "view all content".
I also tried opening the SharePoint 2010 site in SharePoint Designer 2010 but this is not supported. I've used the import method in SharePoint Designer to copy the files and folders to my local drive. But I did not succeed in moving these folders to the SharePoint 2010 site.
What is the supported method to move these documents within their document libraries to SharePoint 2010?
