I just got a seafile server, running version 9. Checking file_updates_sender.log, and I got this:
Warning: File comment has changed since version 6.3, while table
base_filecomment is not migrated yet, please consider migrate it according to v6.3.0 release note, otherwise the file comment feature will not work correctly.
It looks like the old admin didn’t migrate the comment table while upgrading. How to migrate the comment table now?
