I crawled through the admin-, user-, and developer documentation searching for forgotten entries referencing to owncloud instead of nextcloud.
You guys have done a fantastic job updating the heapload of documentation available, but it will not come as a surprise, that there are still some inconsistencies here and there.
For what it’s worth, please feel free to use (and modify) this post as a “to-do” tracker for old name rudiments still present
