Which of the following is an essential checklist item for evaluating migration readiness?

For evaluating migration readiness, a fully configured grid is crucial because it ensures that the infrastructure is set up correctly to support the migration process. A configured grid indicates that the necessary resources, integrations, and settings have been put in place, which can effectively handle the demands of the migration project.

Without a fully configured grid, you risk encountering significant issues during the migration, such as data loss, connectivity problems, and extended downtimes, all of which can derail the entire project. Having the grid ready means that your systems can work seamlessly together, allowing for a smoother transition and better user experience post-migration.

The other options touch on specific areas that may affect migration readiness but do not directly indicate the operational status necessary for a successful migration. For instance, duplicated data can lead to confusion, and lack of training can create user resistance, while unaligned schedules may result in project delays. However, these issues are secondary to ensuring the basic functional framework – the configured grid – is in place.
