CTERA Portal can seamlessly migrate data between storage nodes. This helps you to manage and implement infrastructure changes, hardware retirement policies, and business objectives.

CTERA Portal is a storage-agnostic platform that supports a variety of block and object storage vendors. By abstracting the backend storage using a software-defined storage architecture,

CTERA Portal is able to seamlessly migrate data between on-premises and cloud storage block/object storage nodes.

The migration does not require down time, and instead is performed in the background while the service remains fully operational. Users can continue to access, backup, sync, and share data during the data migration process.

If more than one storage node is connected to the portal, data is migrated to all the storage nodes connected at the time the migration is performed that are not defined as dedicated storage nodes and are write-enabled. For details about defining a storage node as write enabled, the default, see Enabling and Disabling Writes to a Node.

If the source storage node is dedicated to a single virtual portal, its data is migrated only to other storage nodes that are dedicated to the same portal. If more than one dedicated storage node is connected to the portal, data is migrated to all the dedicated storage nodes connected at the time the migration is performed that are write-enabled. For details about defining a dedicated storage node, see Adding and Editing Storage Nodes. For details about defining a storage node as write enabled, the default, see Enabling and Disabling Writes to a Node.
