Prepare all load-sharing mirrors for a major upgrade

Before performing a major upgrade from ONTAP 8.3, you should move all of the load-sharing mirror source volumes to an aggregate on the node that you will upgrade last. This ensures that load-sharing mirror destination volumes are the same or later versions of ONTAP.

  1. Record the locations of all load-sharing mirror source volumes.

    Knowing where the load-sharing mirror source volumes came from helps facilitate returning them to their original locations after the major upgrade.

  2. Determine the node and aggregate to which you will move the load-sharing mirror source volumes.

  3. Move the load-sharing mirror source volumes to the node and aggregate by using the volume move start command.
