The bottom line
Hosting moves done on the fly fail in predictable ways: a database copied hours before cutover loses the latest orders, DNS propagates unevenly so some users hit the old box, a missing cron or environment variable silently breaks a feature, and there's no rehearsed way back. A planned migration removes that exposure. Parity is checked first, data is synced right up to the switch, the cutover is timed and reversible, and the site is verified working before the old environment is retired. The cost of planning is trivial against the cost of a botched move.
