Preparing to update the cluster

Before performing an upgrade or downgrade you must manually check that the cluster is ready, make any required configuration changes, and obtain and install the target ONTAP images.

  1. Verifying that the cluster is ready
    Before you perform the upgrade or downgrade, you should verify that your cluster configuration is healthy.
  2. Preparing the ONTAP software for the update
    Some ONTAP features have configuration requirements that must be completed before the cluster software version can be updated.
  3. Obtaining ONTAP software images
    For ONTAP 9.5 and later, you can copy the ONTAP software image from the Lenovo Data Center Support site to a local folder.
  4. Installing the ONTAP software image
    You must install the target software image on the cluster's nodes.
