Failed to migrate sql errors on upgrade from 6.3.4 to 7.0.2

Hello, I ran the upgrade script to migrate from 6.3.4 to 7.02 like so:
sudo -u seafile ./seafile-server-7.0.2/upgrade/upgrade_6.3_7.0.sh

I received the following output from the script, indicating there were some missing tables it was expecting:

Done

I was able to start the server just fine and everything appears to be in working order, but I’m concerned that my db is corrupted somehow. Can anyone shed some light on what the above tables are used for, and why I might not have them? Do I need to reinstall from scratch?

Thanks
