If you upgrade from Virtuozzo OnApp < 6.2.0-146, run the following steps (1-4).

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
