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.
