[xwiki-users] importing my pages from previous installation

Hello! I've installed xwiki ver 3 through the provided .exe file (Default setting and databases on Windows 7) I had also same xwiki installation on my Fedora 11 (version 2.3) which its home folder had been copied as backup. (according to official guide, xwiki store the pages under xwiki folder in the /home directory/xwiki enterprise/ so I copied the folder for future use) Now, how can I import this backup to my new installation? I don't see anything special?? I tried copying database folder, log file and many other things but nothing... :( how can I import my previous xwiki pages to current version from xwiki directory? ( I just need some pages which I created on that installation) I have copied the directory completely on that time...but now when I copy the database folder to new installation nothing happen.... is there any hope? where xwiki store the pages???? ps. I'm using xwiki as a personal and currently offline.
