Thread:Project:Support desk/Is there a way to take all the pages in a category and change their NS all at once?

I have about ~300 pages in a specific category and I want to move all the pages into a new namespace.

Example:

300 pages in Category:Apples with the NS of HealthyFruit: I want to move all into a new NS called Fruit:

Is there a quick way to do this without an extension? Or am i stuck with manually moving them =P
