We’re trying to upgrade from 11.0.2 to 12.0.4. From the time I entered
sudo -u apache php /var/www/nextcloud/occ upgrade
it’s been just on 5 hours and still going. The database is very busy and I assume it’s doing something
with the oc_filecache entries. If you happen to know what it is doing please let me know -
using some basic SQL a query of oc_filecache shows 34034201 total records, if that helps.
