STEPS TO REPRODUCE
- Create an older instance of XWiki (e.g. 8.4.6)
- Close the instance
- Go to the newer instance (e.g. 11.10.1) and copy/cut the
folder and replace it (first delete the old one) in the same location on the older version
- Start XWiki and follow the Distribution Wizard through the upgrade process
- On Step 3 - Orphaned dependencies, untick all 3 applications: Watchlist Application, Blog Application and Wiki Macro Application
- Click 'Continue'
In 'The following extensions will be removed:' section, nothing is listed, all 3 applications will be made top level (were left unchecked).
Despite being left unchecked, Watchlist Application and Blog Application are listed on this section.
However, the selection for Wiki Macro Application (which is listed as 'Installed as dependency') works properly.
