[xwiki-users] How to move page hierarchy between spaces?

Hi, I've two spaces (let's say, FirstSpace and SecondSpace). FirstSpace contains a page that has child pages like this: FirstSpace +-Parent page +--Child page 1. +--Child page 2. I'd like to move "Parent page" with all children to SecondSpace. However, when I use the rename function on "Parent page", it will not move child pages. Is there any way to do a mass rename (move between spaces) on a set of pages, or it must be done one-by-one? Thanks in advance, Daniel
