Storage Migration

In a Storage Migration scenario, an operator can perform a field upgrade or a hardware replacement of one or more hard drives in a Datto appliance by using the Migrate Storage tool. Consider a Storage Migration if you:

  • Want to expand the storage capacity on your existing Datto appliance.
  • Need to replace one or more of your Datto appliance's hard drives that are in a pre-failure state.

Contact Datto Technical Support if you need to replace a storage component which has failed completely.

Device Migration

In a Device Migration scenario, an operator transfers the entire set of local and cloud backups & device settings from one Datto appliance to another. When performing a device migration, both the source and destination device must be on the same network, in a functional state, and capable of completing all steps in the migration process.

Consider a device migration if you are replacing one Datto appliance with another, and need to transfer all user settings and data from the old device to the new device.

See this article for more information about the Device Migration process.
