I was using XWiki 10.1 Standard Flavor Preinstalled version and now I am tring to upgrade it to 10.2.
I extracted the 10.2 zip to a new location and copy the configuration files and database folder of 10.1 to 10.2, following the guide under http://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Upgrade.
However, I found that under “Global Administration: Notifications”, the newly added feature of 10.2 - overall Default Notifications is not shown. I wonder if the upgrade is successful or not?
