Many thanks Ricardo!! Let me play around first and see how this thing handles then hopefully I'll have a properly functioning wiki after the migration :-) The howto will be posted on it directly as are many other howto's already..

If not I'll switch back to Tomcat/Postgres combo but I'm sure running the system on Solaris or Linux will be much better then my current BSD install as Java seems to spin up the CPU to 100% meaning that from what I've read and the 'top' code of uxtn that I'm getting, tells me that the threads are getting stuck, not being able to address the memory properly.

Even if > going from Tomcat to Glassfish or so?? Yes, I think it is possible to perform a migration, even thought I've never done that. But, yes, I've moved XWiki installations from one server to the other without much difficulty. Provided both systems run the same XWiki release, the problems could only arise from the conversion of the Postgresql database to MySQL. I don't think the servlet container will do a difference once you adjust hibernate.cfg.xml accordingly. A typical XWiki installation, whatever applications you install with it, is divided between file system contents and database contents. All file system contents are locate under /xwiki (though now it is possible to choose the name of its root directory or even call it root) in the applications folder of your servlet container. In the case of Tomcat, it is /webapps. Configuration files (two of them must be surely tweaked, xwiki.cfg and hibernate.cfg.xml) are at /webapps/WEB-INF. Also, stored in the file system are the core libraries, plugins, skins, Velocity templates,... look at this... http://ftp.ebiotic.net/onXWiki/xwiki-platform-eBioTIC.png I've only picked up the XWiki Platform's Architecture illustration from ... http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architecture/WebHome ... and added a box under the components always stored in the database. Note than each time more and more components and configuration settings are being moved to the database or, in the case of configuration settings, could be modified by values in properties of classes stored in the database. Thus, by fully backing up your database and once converted to the system of your choice and by moving the concerned /webapps directory to the new servlet container, functioning must be restored with a minor number of adjustments. Please, take into account that I've never moved XWiki installation across systems, only between boxes running the same servlet containers and relational database manager systems. Many times, different releases of those, but always the same products (MySQL and Tomcat here). I'm sure developers and/or more skilled users will correct this contents and add useful information.

[xwiki-users] Migrating Xwiki
Has anyone ever performed a migration that could give me some advice on how it's done and if what I asked about below is possible? I have checked out this: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Backup which suggests to backup the database but doesn't give any clue to Postgresql! Also is Xwiki content stored in a database or in the /webapps/xwiki instance?? So if I simply backed up and restored the database and copied the xwiki/ dir across to a different platform the system should work?? Even if going from Tomcat to Glassfish or so?? Thanks and regards, Kaya Original Message Subject:Migrating Xwiki Date: Fri, 17 Sep 2010 14:16:08 +0300 From: Kaya Saman To: XWiki Users Hi, I'm wondering if it's possible to migrate Xwiki from one system to another?? I currently run Xwiki on a FreeBSD 8.0 RELEASE x64 platform with 4GB RAM in a dedicated FreeBSD Jail, however I'm having an issue with Java spinning up the CPU to 100% rendering Xwiki inoperable! If I migrate it would be from FreeBSD to either a dedicated FreeBSD system or an OpenSolaris based system on Nexenta. Currently I run Tomcat6 coupled with Postgresql, but would migrate to Glassfish and MySQL. Is it just a matter of backup the Xwiki from the web GUI then restore under Glassfish and convert database from Postgresql to MySQL then attach at other end? Or can I just simply dump the /webapps/xwiki folder into Glassfish or another instance of Tomcat? Thanks for any advice!!
