Upgrading the NetBackup operator

1. Push the new operator images, NetBackup main image, NetBackup media image to container registry with different tags.
2. Run the following script when upgrading from an earlier release of Cloud Scale that used a single helm chart or the kustomize deployment method:

   scripts/prep_operators_for_upgrade.sh

3. Use the following command to suspend the backup job processing:

   nbpemreq -suspend_scheduling

4. Perform the following steps to upgrade the operators:

   • Use the following command to save the operators chart values to a file:

     # helm show values operators-<version>.tgz > operators-values.yaml

   • Use the following command to edit the chart values to match your deployment scenario:

     # vi operators-values.yaml

   • Execute the following command to upgrade the operators:

     helm upgrade --install operators operators-<version>.tgz -f operators-values.yaml -n netbackup-operator-system

     Or

     If using the OCI registry, use the following command:

     helm upgrade --install operators oci://abcd.veritas.com:5000/helm-charts/operators --version <version> -f operators-values.yaml -n netbackup-operator-system

   Following is an example for operators-values.yaml file:

   # Declare variables to be passed into your templates.

     # NetBackup images should be pushed to this registry prior to applying this
