What is the best way to migrate a database from MS SQL to PostgreSQL?

Question

PostgreSQL

The management decided to switch to PostgreSQL. All old projects are on MS. Actually, I'm interested in a tool that will help you quickly transfer everything from MS SQL to PostgreSQL. Google search led to DBConvert but he does not want to be friends with Cyrillic. What other options are there for this?

Answer 1

try pg_loader .
But if the DB is big and complex, I wouldn't rely on automatic tools

Answer 2

Try to convert the structure, correct it by hand.
Unload data in csv, upload to postgres.
