This content describes how to upgrade storage controllers in an AFF A700 HA pair with new AFF A900 controllers, while keeping all the existing data and disks. This is a complex procedure that should be used only by experienced administrators.

You should use this guide under the following circumstances:

  • You have verified with your NetApp sales representative that you have received an AFF A900 controller module, NVS, and the parts required for the upgrade.

  • You are running ONTAP 9.10.1 RC2 or later.

  • 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 should NOT use this guide under the following circumstances:

  • If you are using FlexArray Virtualization Software on AFF A700 systems, do NOT use this procedure.

  • If you are using a shared switch for cluster-interconnect and Ethernet attached storage, do NOT use this procedure.

For upgrading Fabric MetroCluster or MetroCluster IP configurations, refer to References to link to the MetroCluster Upgrade and Expansion content.

Note You can use NetApp Storage Encryption (NSE) and NetApp Volume Encryption (NVE) 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.
