After upgrading from xwiki:16.10.8-postgres-tomcat to xwiki:16.10.10-postgres-tomcat (latest LTS), the following warning appears at the top of the wiki.
When I click on Categories Location Migrator and complete the migration, the tool shows a “done” message. However, the warning banner still remains and never goes away.
This issue only happens on the main wiki, it does not appear in subwikis.
Do you have any idea why the warning does not disappear after migration?
Is your blog version 9.15 or 9.15.1 ? There was a bugfix that was applied in 9.15.1.
Otherwise, I would check if all the categories are in the located under Blog.Categories.
If there is one that is in the old location Blog that will be the reason to notify there are still categories to migrate.
You can do this check in main wiki as well as in sub-wikis.
The problem was that one of the subwikis was using an old blog feature and the error in main wiki was not referring to it.
So, It might be better to improve the error message but I just upgraded the blog in this subwiki, ran the migration there and now the error in main wiki is gone. Thanks for your support!
