Software images are specific to platform models.

You must obtain the correct image for your cluster. Software images, firmware version information, and the latest firmware for your platform model are available on the MySupportPoral site.
Software images include the latest version of system firmware that was available when a given version of ONTAP was released.
If you are downgrading a system with Volume Encryption from ONTAP 9.7 or later, you must download the ONTAP software image for non-restricted countries, which includes Volume Encryption.

If you use the ONTAP software image for restricted countries to downgrade or revert a system with Volume Encryption, the system panics and you lose access to your volumes.
1. Locate the target ONTAP software in the MySupportPoral site.
2. Copy the software image.
  - For ONTAP 9.7 or later, copy the software image (for example, 97_q_image.tgz) from the MySupportPoral site to the directory on the HTTP server or FTP server from which the image will be served or to a local folder.

Install the software image

You must install the target software image on the cluster’s nodes.

If you are downgrading or reverting a system with Volume Encryption from ONTAP 9.7 or later, you must have downloaded the ONTAP software image for non-restricted countries, which includes Volume Encryption.

If you use the ONTAP software image for restricted countries to downgrade or revert a system with Volume Encryption, the system panics and you lose access to your volumes.
1. Set the privilege level to advanced, entering y when prompted to continue: set -privilege advanced
  
  The advanced prompt (*>) appears.
2. Install the software image on the nodes.
  
  This command downloads and installs the software image on all of the nodes simultaneously. To download and install the image on each node one at a time, do not specify the -background parameter.
  - If you are downgrading or reverting a non-MetroCluster configuration or a two-node MetroCluster configuration:system node image update -node * -package location -replace-package true -setdefault true -background true
    
    This command uses an extended query to change the target software image, which is installed as the alternate image, to be the default image for the node.
  - If you are dowgrading or reverting a four or eight-node MetroCluster configuration, you must issue the following command on both clusters: system node image update -node * -package location -replace-package true true -background true -setdefault false
    
    This command uses an extended query to change the target software image, which is installed as the alternate image on each node.
3. Enter y to continue when prompted.
4. Verify that the software image is downloaded and installed on each node: system node image show-update-progress -node *
  
  This command displays the current status of the software image download and installation. You should continue to run this command until all nodes report a Run Status of Exited, and an Exit Status of Success.
  
  The system node image update command can fail and display error or warning messages. After resolving any errors or warnings, you can run the command again.
  
  This example shows a two-node cluster in which the software image is downloaded and installed successfully on both nodes:
  cluster1::*> system node image show-update-progress -node * There is no update/install in progress Status of most recent operation: Run Status: Exited Exit Status: Success Phase: Run Script Exit Message: After a clean shutdown, image2 will be set as the default boot image on node0. There is no update/install in progress Status of most recent operation: Run Status: Exited Exit Status: Success Phase: Run Script Exit Message: After a clean shutdown, image2 will be set as the default boot image on node1. 2 entries were acted on.
