I am currently in the process of migrating from H2 db to AWS RDS postgres instance. I have a metabase running in docker container on a custom server using the H2 db, which I would like to get the dashboards out of. Then I have another metabase app running in EKS, which uses AWS RDS. The AWS metabase is empty, there are no dashboards I have only added some users.
If I migrate the H2 db now to AWS RDS, does it complete overwrite the existing db? Is there a way to migrate only specific parts like dashboards/questions? Does the migrate-to db have to be empty completely?
