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#HUpgradinga...
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

I've not tried myself any upgrade in the 2.y series. I did that in the 1.y one. I found some migration issues solved with the help of the dev community. By reading this document, I can only conclude that it is possible and safe to do that. But I've no experience with this exact process. I'm currently involved in a 1.y to 2.y migration. Different main releases, different databases releases, different servlet applications releases, different servers. In this case, a lot of problems mainly related with attachments have been found. In addition to the concerned AdminGuide section, I would recommend to check the health of the attachments database by using... http://code.xwiki.org/xwiki/bin/view/Snippets/AllBrokenAttachments ... prior the update. I've not checked the release notes from 2.2.x. to 2.5 releases myself. That's all I can say. Thanks.
"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!
