I’ve decided to upgrade old Nextcloud 12 which I was using for a while to version 13 but I’ve experienced some issues. I think the problem is caused by big oc_filecache table so upgrade is stuck 48+ hours.

mysql> show table status like "oc_filecache"\G;

Is there anything I can do about this problem?

Do you and your users have around 14 mio files and folders (roughly)? It could be that some clean-up routines are not working, check on the admin interface when the cronjob was run for the last time.

Please upgrade from NC13 through to NC15 or later to run a supported version.
