Just updating nextcloud to latest version (10.0.1) and proceeded to follow the upgrade instructions - however I seem to have hit an issue since it it spending a long time performing “Fix classification for calendar objects” and looping through all LDAP users and we are not even using calendar events (and only a few users at the moment have ever logged into the system via LDAP).
I see OwnCloud has a Github issue on the topic: https://github.com/owncloud/core/issues/25617
Can changes performed in OwnCloud post fork be ported across to NextCloud?
