Patch Installation

The instructions below are relevant if you already run Virtuozzo OnApp 6.2.

Upgrade Control Panel Server

If you upgrade from Virtuozzo OnApp >=6.2.0-146, run the following command:

To upgrade your Control Panel server:

Upgrade Virtuozzo OnApp Control Panel installer package:
1
# yum update onapp-cp-install

Update your server OS components (if required):

1
# /onapp/onapp-cp-install/onapp-cp-install.sh -y

(Optional) If you need some custom Control Panel configuration, set the values before the installer script runs.
