I think we need more detailed instructions for moving data from an existing DB to a new DB. I've just added the MySQL instructions and a glimpse of Oracle (just use exp and imp), I have no worked on in other databases to put some instructions. Eventually anyone that have used PosgreSQL or any other RDBMS could add the instructions (or just drop me a line and I can add it to the wiki) The exporter would be the best way to do that but importing a large XAR doesn't work either when the memory is not large enough so import at the DB level is required anyway for some large XWiki installs. The problem with this comes from XWiki having code at the page level, so if we make a bulk copy (as in the instructive) not a complete upgrade is made. My feeling is to let both migration path coexist so that anyone can choose which one to use (I'm not sure this is a good idea, but in the meantime the database copy is left into the migration path) -- Víctor A.

[xwiki-users] More on upgrade from 0.9
Hi all, as anyone can see there's a first attempt to upgrade from v0.9 in http://www.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgradinganXWikiv09Installation The problem with this approach is that it just migrates the Java code, but not the one inside the xwiki pages stored in the database. In order to construct a strong and complete migration process I need some help (as usual :-D), mainly : * what pages/spaces contain code that is considered part of XWiki distribution ?? * does anyone has success in making the code at http://old.xwiki.org/xwiki/bin/view/Test/ImportExport work on 0.9 ?? * any other places to look at for other pieces of XWiki core that should be added to the upgrade guide ??

I missed something here :P The problem si that XWiki core isn't just Java, it also contains code inside the XWiki pages. e.g. if I install a new servlet container (with XWiki 1.1 inside it) and a new database where I copy the old one, this installation has new Java code and old wiki code. A typical example is the page that generates the RSS feeds (RssFeed, I think) * does anyone has success in making the code at http://old.xwiki.org/xwiki/bin/view/Test/ImportExport work on 0.9 ?? Yes Please, tell me how, because I discovered two problems : two missing javascript files in 0.9 (they' re part of 1.1) and getURL seems missing from the 0.9 API (I'm not completely sure). Perhaps there's more ... who knows ?? * any other places to look at for other pieces of XWiki core that should be added to the upgrade guide ??

BTW, if you find any error don' t hesitate in correct it, and *please* don't use th WYSIWYG editor because it has problems with some tags. What's next? ;) I think that after that Export Import work it' s piece of cake. Two of the three main pieces are already easy to migrate (code and skins), we need only to extract the pages that are not part of XWiki code from one database and put it in the new one !!!
