Migrate a SharePoint Team Wiki to an Enterprise Wiki

Perhaps someone has also migrated his old SharePoint 2007 Team Wiki to SharePoint 2010 and wants to have the cool features from an Enterprise Wiki.

I searched a while and I think the best way to do this is to migrate with PowerShell. The List Wiki and the Enterprise Wiki are using different fields so there will be no other way I thing but PowerShell or manually.

So the great script for your use. Just adapt the settings for your environment.

 $pageFolder    = "/Seiten/"
