PSQL。 将数据从一个数据库迁移到具有不同表结构的另一个数据库

Question

I have data on a PSQL-db that I need to migrate to another PSQL-db. The biggest problem is that the structure of the DB's is different.

So my question is what is the smartest way of doing this kind of migration?

My initial thoughts was to map where all the data should go in the new DB in a excel sheet and then write some kind of script that inserts the old data into the new DB.

This seems a little tedious and i'm wondering if anyone know any tool or methods to make this easier/faster?

Answer 1

You can create new table with an extra field that show

imported

Get data from another db and then create a view of both tables.
