Hi Yishay, Yishay Mor wrote: Yes, you are admin of your wiki on myxwiki.org. Go in Administration -> Import There should be no problem if you take care. If you don't want to upgrade the whole XE, you can take just the administration application from here http://maven.xwiki.org/releases/com/xpn/xwiki/platform/applications/xwiki-a… to solve this issue Just make sure you exclude the group documents (XWikiAdminGroup and XWikiAllGroup) from the list by un-checking their boxes. Beware if you forget this is not that easily reversible (but your XWikiAllGroup can be re-created by script, though, you'll have to do the AdminGroup manually). For all other groups you created yourself, you have nothing to worry about, they are kept safe. What the upgrade will do is update the group sheet (XWiki.XWikiGroupSheet) so that it asks for the proper javascript library to be loaded. Don't forget to exclude XWiki.XWikiPreferences, too, as you probably customized it. Jerome.
