I am currently tracking a red flag issue at one of our customers.
The customer has been trying to use a team site like file store. Moving files and folders around as a workflow using Explorer View. As the system was only at SP1 it hit a little known bug of running out of document IDs, which apparently change each time a document is moved in explorer view. This then led, somehow, to a corruption of the Document Library so that its contents could not be exported using STSADM.
The issue has been escalated to Microsoft and is in the hands of a Microsoft ‘SharePoint Escalation Engineer’. The solution appears to be to map the doclib to a drive letter in WebDAV and Robocopy the documents out of it to file store. This is then Robocopied into a new doclib in a new site on a staging Farm by means of the same WebDAV mechanism. The Escalation Engineer has hacked together some code to extract the permissions in the source Farm into an XML file and then apply them to the target Farm. I believe that just to make things even more complex the source and target Farms are in different AD domains.
I have lots of doubts about this process, so lets discuss! 🙂
