A device migration is the process of moving data from one device to another. Device migrations are usually in response to either hardware corruption or device upgrades and, to a much lesser extent, load balancing. The original device must be able to perform the tasks necessary for a device migration.
Generally, device migrations transfer at roughly 1TB per day. Network speeds or device-to-device connections will affect this rate.
Data migrations cannot be performed while any restores are active on the source appliance. This includes file restores and virtualizations. You must remove all restores before initiating a device migration. Restores cannot be migrated.
Be sure to have the new device in-hand and to check that both devices are checking in before initiating the migration process.
