Not pulling document properties when moving a Document Library

Question

I'm attempting to move a very large Document Library from SP2007 to SP2010 but I cannot get the Properties of the Documents to move with the files. The library is too large to export as a Template with Data, so I've been attempting to move things over using the Windows Explorer Feature in both 2007/2010.

I've noticed that some Documents in the library migrate fine, but others dump all of the properties.

Is there a way I can completely duplicate a large document library without losing the properties of each document?

Answer 1

Have you tried the Content Deployment Wizard to do this?

Answer 2

Windows Explorer will pull over the previous versions of the file as long as the document libraries both have versioning on, but they won't retain the metadata properties to it. What I would suggest is make a powershell script to do the metadata pulling for you, but since you are going from SharePoint 2007 to SharePoint 2010, that might be much harder. You could write a VS application that will pull the documents in from Lists.asmx web reference, and post them on the SharePoint 2010 server programmatically.

Here's a good start on where I would look.
