  Hi,
 Just a simple question: can I safely upgrade XWiki from a 2.2.x version to a 2.5.x (or
newer) release, without upgrading step by step (e.g. go to 2.3.x ... , then 2.4.x ...
2.5)?
 
 Following this document...
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgrading…
 It must be safe to do what you are planning to do provided you review
 those additional operations and are particularly "observant" with the
 WARNINGS on that file. As you can read... 
Sorry, but that didn't answered (nor the related page) if it safe to
jump from version 2.2.x directly to last 2.5 version
Arnaud.
 "Note that the database schema is automatically upgraded when needed.
 All you need to do is to ensure your xwiki.cfg file is correctly
 configured to perform the migration."
 And, of course, backup your database and /xwiki application folder
 before proceeding!
 Hope this helps!
 Ricardo
