What is a requirement for what can be migrated during batch migrations in VPLEX?

The requirement that the source and target LUNs must be identical during batch migrations in VPLEX is crucial for ensuring data consistency and integrity throughout the migration process. By requiring the LUNs to be identical, VPLEX can effectively manage the data transfer without introducing complications that might arise from differences in LUN characteristics, which can include configuration settings, size limitations, or LUN performance characteristics.

When LUNs are identical, it simplifies the management of the underlying storage resources, allowing VPLEX to maintain an accurate mapping of data blocks and ensuring that the migration is seamless. This identicality aids in avoiding potential issues such as data corruption or loss that might occur if source and target LUNs have diverging configurations or formats.

Thus, this requirement directly supports the principal focus of VPLEX on ensuring availability and data protection during the migration process, making sure that all necessary parameters align to facilitate a successful and efficient data transfer.
