I have read all documentation and don't fully understand how to move code (apex classes, visualforce pages) to production from a sandbox.
Can someone give a full process user guide how to do that?
In Eclipse I just authorize a sandbox, then select apex classes and press deploy to Production. And after authorization runs all test and code successfully moves to production system.
I'm confusing in scratch orgs and etc.
For now, I create a project with manifest, authorized in sandbox, and retrieved metadata in manifest. What's the next steps?
