Decide whether to upgrade by moving volumes or storage

Contributors netapp-pcarriga

This content describes how to upgrade the controller hardware of an AFF, FAS, or ASA system in a cluster by moving storage or volumes.

Use this procedure if you want to upgrade controller hardware in the following situations:

Note The hardware upgrade procedures have been simplified in ONTAP 9.8 with the introduction of the automatic port placement feature.
  • Your original and new nodes are compatible and supported.

  • The original and new nodes are running ONTAP 9.0 or later. NetApp recommends, when possible, that you have the same ONTAP version running on the original and new nodes.

    If your controller upgrade includes mixed ONTAP versions, see Mixed version ONTAP clusters for more information.

  • You are reusing the IP addresses, network masks, and gateways of the original nodes on the new nodes.

  • You plan to upgrade controller hardware by moving storage or moving volumes.

  • You are prepared to perform a disruptive procedure if you are upgrading by moving storage.

    Upgrading by moving volumes is nondisruptive.

  • You plan to convert a node of a supported model to a disk shelf, and then attach it to the new nodes.

If you are upgrading a MetroCluster configuration, see Upgrade, refresh, or expand the MetroCluster configuration.
