Used to have version 4.14.0 with PostgreSQL as database
Decided to upgrade to 4.14.5 using this approach
After this all content that was inserted previously has gone (collections etc.)
Why could this happen? Are there any issues or tricks that needs to be reviewed before upgrading application?
This seeems to be due to using Docker contaiiners in Kubernetes environment. Locally everything works ok. Need to think of how to upgrade it in K8 environment without loosing collections etc
