Change master language for all pages in CMS 10

Vote:
 

We are working on a CMS/Commerce project and have crated a lot of pages in the cms tree. Late in the project, the customer decided that master language should be another than previously decided, hence all pages are created with the wrong master language. Is there any easy, and safe, way to change master language for all pages, or do we have to create them from scratch?
