What type of data can be migrated with device migrations?

Data migration with device migrations encompasses the transfer of data between dissimilar arrays. This capability is crucial for organizations seeking to evolve their storage infrastructure, allowing them to take advantage of different storage technologies, features, or performance characteristics.

When migrating data between dissimilar arrays, it is possible to redistribute workloads effectively, enabling flexibility in deployments and aligning storage with current business objectives. This supports scenarios like data center consolidations, hardware upgrades, or the integration of new technology into existing environments, which often require moving data from one array type to another.

Each of the other choices reflects a limitation that does not accurately represent the full scope of device migration capabilities. For instance, only migrating data between identical arrays would restrict organizations, as they might miss opportunities to optimize and modernize their storage solutions. Similarly, focusing solely on hot volumes reduces the scope of migration to only active data, which may not be suitable for all situations. Lastly, migrating data across the same cluster assumes uniformity in array technology, therefore limiting versatility in leveraging various storage systems for optimal performance.

In summary, the ability to migrate data between dissimilar arrays is a significant feature of device migrations, enabling adaptability and modernization in storage management practices.
