Migrate Postgres Database

Hi! I want to migrate my Postgres database to a new LoRa Server so as not to create everything again.
I do the pg_dump with the tables loraserver_ns and loraserver_as, but when I login in the LoRa App Server I dont have everything that I have in my other server.
What I exactly have to do? Thank you!
