2.4. Upgrading Virtuozzo PowerPanel


Virtuozzo PowerPanel services may need to be stopped and restarted during upgrade, resulting in a certain downtime.

Virtuozzo PowerPanel can be upgraded to a new version with the following commands:

# yum update vzapi-installer
# vzapi-installer upgrade <upgrade_package>

Where <upgrade_package> is the URL of a specific pp-release package that installs a repository for a specific upgrade. The URL becomes available when an upgrade is released.

The upgrade process requires no other interaction from the administrator. All the necessary changes are automatically made to both the controller and all computes.
