DB Migration

i have mysql db on server A, nocobase app(2.0.16-full) on server B

i am migrated mysql from server A to C, now trying to point the application in server b to mysql db on server C with same app version but i got error "key column ‘collection_name’ does not exist’ as App error while docker builds

How to solve this issue, i have checked there is no column collection_name in db in server A(existing)

Hello, you need to copy the previous docker-compose.yml file, only changing the database section, and not changing anything else. Your problem is caused by an inconsistency in the DB_UNDERSCORED environment variable.
