Hello, I'm sorry but I'm completely confused about upgrade on myxwiki.org :-( . When I enter in the Wiki admin pages I see a warning message at the top asking me to perform an upgrade of the XAR: "*December 29: Upgraded xwiki to version 4.4-rc-1. Don't forget to upgrade your wiki with the new XAR file <http://maven.xwiki.org/releases/org/xwiki/enterprise/xwiki-enterprise-ui-all/4.4-rc-1/xwiki-enterprise-ui-all-4.4-rc-1.xar> (Upgrade instructions <http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Upgrade#HUpgradingwikidocuments>).*" Rather than importing the xar file I would prefer to use EM (Extensin Manager) because my Wiki has already been customized and I want to manage "conflicts". When I search with EM "standard" search, all extensions are already upgraded to 4.4-rc-1 version: for instance "XWiki Platform - Extension - Script / 4.4-rc-1 / Installed by default" => so do I realy need to upgrade? Due to Thomas answer (see below) I've tried to use advanced search in EM but it doesn't show any results, what should I search for? ("4.4*" or "upgrade/" return no results). Also in answer below Thomas suggests that it's possible to update Wiki (on myxwiki.org only?) to any version thru EM, for instance am I able to upgrade to the latest xwiki-enterprise-ui-all-4.5-rc-1.xar <http://www.xwiki.org/xwiki/bin/view/DownloadCode/DownloadFeedback?downloadLink=http://download.forge.objectweb.org/xwiki/xwiki-enterprise-ui-all-4.5-rc-1.xar&projectType=Latest&projectVersion=4.5-rc-1&projectID=1>? Thanks for your clarification (it's hard to be a newbie) Le 11/02/2013 09:05, Thomas Mortagne a écrit :

Thanks Thomas for this clear answer ;-). I have performed the upgrade thru EM and everything works fine (some customizations have been erased during the upgrade process because I'm not familiar with XWiki structure and I didn't answered merge conflicts correctly, for instance all my WYSIWYG Editor seetings have been dropped off ... I will do them again). By the way my understanding is that each time myxwiki.org will be updated I could check the mailing list or "my" Wiki footer or the info box on top of all admin pages to know the exact XWiki version number of the WAR and then update the XAR accordingly has described below with EM by my own?

Ok thanks. I have a last question regarding XWiki update process. Does the XAR I have installed thru the EM / Advanced Search "org.xwiki.enterprise:xwiki-enterprise-ui-all" contains absolutely all XWiki pages? Which means I can "skip" updates for some versions because next XAR update will be a "full" update. But it also means, when I perform an update that I'm prompted to solve conflicts for pages which are in the XAR but which, in fact, didn't changed from an XWiki official distribution point of view (the only changes in these pages are the changes I've performed). Or does the upgrade process is more clever: each page has its own version and the update process does a comparison between the current page version in my Wiki and the one coming from the XAR before prompting to solve a confict? To put it in a nutshell: does the updated XAR / or the update process performs an incremental update or does it, potentialy depending on the admin answers on conflicts, updates all Wiki pages? Thanks for your (I hope) last explainations,

Nice: the annonced feature is now available and working perfectly. It's easier than ever to upgrade XWiki pages after an admin has performed the WAR update => I've done it with success on myxwiki.org. Thanks to the dev :-) Le 14/02/2013 08:29, Thomas Mortagne a écrit :
