[xwiki-users] [1.1] "With history" import option

Hello, I would like to know how the option "with history" in the import tool should be understood ? Does it mean : - history of existing pages will be preserved (new revision added for last revision of imported page) - history of imported pages will be preserved and replace local pages history - history of imported pages will be preserved as well as local pages history (concatenation) I added a line for this in the admin guide, but need to detail the exact way it works (btw I need to be sure of how it works before importing pages in my own wiki ;-) ) http://www.xwiki.org/xwiki/bin/view/AdminGuide/ImportExport Thanks, Jeremie
