Which consideration is crucial when migrating devices in VPLEX?

When migrating devices in VPLEX, a crucial consideration is that the target device must be the same size or larger than the source device. This requirement ensures that all the data from the source device can be accommodated in the target device, preventing data loss during the migration process. If the target device is smaller than the source device, there would not be enough space to hold all the data, which could lead to migration failure and potential data corruption.

Understanding this requirement is essential for ensuring a smooth migration operation without interruptions or errors. Additionally, while there are other important factors to consider during migration, such as device consistency and the potential for downtime, the sizing requirement is fundamental to successful migration in VPLEX environments.
