[xwiki-users] XWiki migration and extensions

Hi, I have XWiki running in a test environment, and want to move to another server for production. Currently I have deployed it by extracting the war file in a jetty server and a mysql database, and there are some extensions installed using the extension manager. To migrate to another server, is it sufficient to migrate the database and use a new war file in the new server, do I need to use the same xwiki folder inside webapps? In other words, does installing extensions add files to the file system? Thanks
