This guide walks through upgrading Portworx deployed on DCOS

Upgrade the Portworx image in the systemd service file

On each agent node where Portworx is installed, edit the /etc/systemd/system/portworx.service file and change the docker image tag for the Portworx image to the desired version. For instance if you want to upgrade from 1.2.9 to 1.2.10, change “portworx/px-enterprise:1.2.9” to “portworx/px-enterprise:1.2.10”

Restart the Portworx service

sudo systemctl daemon-reload
sudo systemctl restart portworx

Restart the node if required

Upgrades between some versions require a reboot of the node. If a reboot is required, Portworx will be in initializting state after the service restart. The Portworx logs will also mention that a reboot is required.
