This content describes how to upgrade the storage controllers in an HA pair with new controllers while keeping all the existing data and disks. This is a complex procedure that should be used only by experienced administrators.

Use this content under the following circumstances:

  • You do not want to add the new controllers as a new HA pair to the cluster and migrate the data using volume moves.

  • You are experienced in administering ONTAP and are comfortable with the risks of working in the diagnostic privilege mode.

  • You have a system that uses Fabric MetroCluster 4-node and 8-node configurations running ONTAP 9.5 or earlier.

Note You can use NetApp Storage Encryption (NSE), NetApp Volume Encryption (NVE), and NetApp Aggregate Encryption (NAE) with this procedure.

If you prefer a different method of upgrading the controller hardware and are willing to do volume moves, refer to References to link to Upgrade by moving volumes or storage.
