Xar is a set of wiki pages that is stored in the database. When you restore your old backup - you automatically end-up with previous version of xar. So you DO need to import the new xar file, but as Jerem validly pointed (!) see that you don't override your custom settings (simply do not import those pages OR try to re-apply the changes on new pages).

Well maybe not exactly the case here since page customization has been done. But for cases where simple settings tuning has been applied there is one flaw in upgrade process that drives me crazy. If I choose not to import some pages (those I have custom settings in) that were improved in newer release - I may not get all the benefits of new release, or even worse - I may have half-working system in case other pages that I did reimport from new release rely on the NEW behavior of not-upgraded page. This is complex problem, it's not just enough to separate the settings values from presentation to freely upload full new XAR because settings keys also change once in a while. It might require identifying which pages were custom modified and provide means of merging those with new ones. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of jerem Sent: Friday, January 13, 2012 09:39 AM To: [email protected] Subject: Re: [xwiki-users] Which is the best strategy when migrating from one wiki version to another wiki version? Approach 2 is good, when the 3.3 webapp will start, if database schema was changed it should be updated automatically - you just have to take care of setting correctly the properties for this (see here : http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgradingXWikiCore) What is left is to report also any modification you would have done the the properties (xwiki.cfg, hibernate hbm, ...), and to reimport the standard 3.3 xar. For import, you should be careful not to import the standard pages you would have customized, or if you import them you will have to customize them again. Another approach would be to migrate your existing instance of 3.2 to 3.3, and just perform a database backup previously, but of course it means possible interruption of service. -- View this message in context: http://xwiki.475771.n2.nabble.com/Which-is-the-best-strategy-when-migrating-from-one-wiki-version-to-another-wiki-version-tp7181050p7183276.html Sent from the XWiki- Users mailing list archive at Nabble.com. _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
