The part you quoted does not talk about buggy code. Bugs will always exist, the idea is to prepare for them. Migrate systems incrementally, run versions in parallel, have tested rollback strategies at every step, so on and so forth. Not cut corners on backups and contingency plans. Don't rush to launch.

Buggy code is not the problem, but a buggy process is.
