For successful migration, how must devices be handled in VPLEX before migration?

For successful migration in VPLEX, devices must be removed from consistency groups prior to migration. This is essential because consistency groups are designed to ensure data consistency across multiple devices during operations. When devices are part of a consistency group, they are tightly coupled, meaning any operations, like migrations, would require synchronization among all devices in that group. Removing devices from consistency groups ensures that migration can be performed without the constraints of maintaining consistency across multiple devices, enabling smoother transitions and reducing the risk of data inconsistency or outage during the migration process. This step is critical for ensuring that each device can be handled independently during the migration, allowing for a more efficient and orderly process.
