Including a schedule for parallel operation of the old and new systems in a system migration plan is crucial for several reasons. This approach minimizes disruptions and allows for a smoother transition. By running both systems in parallel, organizations can validate that the new system is functioning as intended before fully decommissioning the old one. It offers an opportunity to perform live testing, ensuring that all functionality is preserved and that users can transition without losing access to critical services or data.

In addition, having a predefined schedule for this operation helps coordinate resources, manage user expectations, and provides a clear timeline for when both systems will operate simultaneously. This mitigates risks associated with migration, such as data loss or functionality gaps, and allows for addressing any issues that arise during the testing phase before fully committing to the new system.

This choice encapsulates a comprehensive strategy for successful migration, ensuring that stakeholders have confidence in the new system's viability while maintaining operational continuity.
