Explanation

A back-out strategy (rollback plan) is essential when performing large-scale changes under a strict timeframe. If something goes wrong during the overnight refresh, a back-out plan allows Joe to quickly revert systems to their previous working state before business hours begin, ensuring zero downtime. Taking disk images of every replaced computer is a good practice but does not address the risk of the refresh failing mid-task. Skipping every other computer is not a risk mitigation strategy. An offsite warm site is for disaster recovery scenarios, not a planned maintenance window. A solid back-out strategy is the primary safeguard for change management operations with hard deadlines.
