[xwiki-users] xwiki backup/restore

Hi Everyone, We have a very old version of xwiki installed on a linuxbox, by a previous admin who installed it manually with mysql and tomcat. I've installed the latest version of xwiki (1.7) onto another box using the standalone installer, and I'm trying to import all the xwiki pages from the old box to the new one. From what I've read, the standalone installer uses its own hypersonic sql, and I'm having trouble figuring out if and how I can import the old files to the new one. Is there a way to consolidate a mysql dump to a hypersonic database? I've also tried exporting the XAR file from the old xwiki and importing into the new one through the web interface, but I'm getting a max_uploadsize error (I've already tried changing the limit in the Preference class editor, but it still gives me the same error). I've been stuck a while, and I feel like I've run out of options. Does anyone have any suggestions? Thanks, James
