Upgrade Version 5.03 to 11.10.1218

Is it possible to update XWIKI directly from version 5.03 to 11.10?

You’ll need to read every release notes to see if there are things to do. That’s a lot.

Alternative: https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Upgrade#HAlternativeStartfresh2CplusExportandReimportyourdata

Recommendation: always upgrade when there are new versions and don’t stay on an old one for long :wink:

It should work but it depends a lot on the number of customizations you have made to the standard pages.

I would recommend to try the standard upgrade process before https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Upgrade#HAlternativeStartfresh2CplusExportandReimportyourdata since this one usually create more problems than it solve and is to be used as last resort.
