I have a standard task list in SharePoint 2007, which is hosted by a third party. I cannot do an in-place upgrade on the 2007 instance. I have a locally hosted and running SharePoint 2010 instance. How can I most easily export a task list from SharePoint 2007 into SharePoint 2010?
If you have only one list to migrate, the easiest might be to create a new task list on your SP2010 instance, and use the edit in datasheet mode in order to copy the data.
If you have many lists to move, you might have to write some code that would retrieve the data from your thirdparty-hosted SP2007 instance via SP built-in web services and push it the new instance.
