We have recently followed the upgrade path from 3.X to 5.0.3 to 6.1.1 but it seems that something broke along the way.
Although Confluence starts, it throws this error:
2018-09-14 10:32:18,031 ERROR [localhost-startStop-1] [atlassian.confluence.setup.BootstrapApplicationStartupListener] checkConfigurationOnStartup Detected tables with non-default character encoding. See https://confluence.atlassian.com/x/TABrFw
I made sure that all tables and columns use UTF8 as per that page but I think the problem has more to do with missing tables.
For example, I only have 58 total tables, I lack the user_mapping table and probably others.
Is this the issue and if so, how can I fix it ?
