How to update, upload a 1s Bitrix database dump from a test server to a combat 1s Bitrix without data loss?

Question

1C-Bitrix

Hello, maybe someone has come across this, there is a test server with 1s Bitrix, there is a combat one, and there and there changes are made to the database, how do you do it so that one dump does not overwrite another, because Bitrix has a bunch of tables and where what he writes down is basically a secret, plus through the admin panel content managers can add something to the database, and the database versions will be very different

Answer 1

To be sure that the database structure will not differ, you need to work through migrations.

Answer 2

turn off the site at night for everyone except admins and upload

Answer 3

and if I overwrite the data of the content managers with my test ones?
