Upgrade Portworx Backup

Portworx Backup supports upgrades to version n from versions n-1 or n-2 versions. For example, if you are on Portworx Backup version 2.4.x, you can directly upgrade to 2.7.x. Suppose, if you are on 2.3.x and you wish to upgrade to 2.7.x, you need to upgrade in phased manner. Firstly upgrade from version 2.3.x to 2.5.x, and then upgrade from version 2.5.x to 2.7.x.

To upgrade from Portworx Backup version 2.4.x or 2.5.x to 2.7.x, you can just use the px-central chart.

KDMP backup behavior for upgrades

Assume that you are on Portworx Backup version 2.6.0 or below, with cloud native driver installed on your application clusters. When you upgrade to Portworx Backup version 2.7.x and above from previous versions, the existing manual backups will not be affected:

The backups that are scheduled (to be created in the future) with the cloud native driver:

  • Get migrated to CSI snapshots along with offload to backup location option if volume snapshot class is available

  • Utilizes KDMP driver to create a direct KDMP backup if volume snapshot class is not available


Scheduled backups that were created using cloud native driver before the upgrade will only get migrated and not the ones that are created after upgrade. Scheduled backups created with other drivers remain unchanged. One of the backup might fail after migrating native driver to CSI + Offload if the reconciler has not updated the schedule CR.

Below sections guide you to upgrade your Portworx Backup (in internet connected and air-gapped environments) and Stork component.
