I'm working with a customer that needs to migrate documents from their current document management system (not Sharepoint) into Sharepoint MOSS 2007 retaining document history and metadata. I've written a proof of concept using the Sharepoint web services and that looks promising, but the snag so far seems to be programmatically setting the created date/time and user. The webservices allow the fields to be set but implicitly override them to be the currently logged in user + date/time. For obvious reasons, I need to be able to keep the original created date/time and user on migration. Does anyone know the best way to approach this problem?
