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.
