Preparing for NetBackup upgrade

1. Take a backup of all the NetBackup jobs and ensure that all the jobs are suspended.
2. Take a catalog backup.

   See Backing up a catalog.

3. Copy DRPackages files (packages) located at /mnt/nblogs/DRPackages/ from the pod to the host machine from where AKS cluster is accessed.

   Run the following command:

   kubectl cp <primary-pod-namespace>/<primary-pod-name>:/mnt/nblogs/DRPackages <Path_where_to_copy_on_host_machine>

4. Preserve the data of /mnt/nbdata and /mnt/nblogs on host machine by creating tar and copying it using the following command:

   kubectl cp <primary-pod-namespace>/<primary-pod-name>:<tar_file_name> <path_on_host_machine_where_to_preserve_the_data>

5. Preserve the environment CR object using the following command and operator directory that is used to deploy the NetBackup operator:

   kubectl -n <namespace> get environment.netbackup.veritas.com <environment name> -o yaml > environment.yaml

   Note:

   Ensure that you upgrade MSDP operator first.

6. In case of existing NetBackup deployments with Azure disks, change the storage class for catalog and log data of primary server to trigger data migration. For more information on changing the storage class, refer to the AKS-specific requirements sub-section of the following section:

   See Preparing the environment for NetBackup installation on AKS.
