You can’t do it without automating your entire build,
deploy, test, and release process.
You can’t do it without a comprehensive, reliable set of
automated tests.
You can’t do it without writing system tests that run
against a production-like environment.

That’s why, even if you can’t actually release every set of
changes that passes all your tests, you should aim to
create a process that would let you do so if you choose to.
