You should use the standard upgrade procedure whenever possible to ensure you have the latest features and fixes. Only use the custom upgrade when you have a specific reason for installing an older version.
With OnApp you can upgrade to a custom CP version, i.e. not the latest one available in production. Make sure to update within the same major version. For example, you can upgrade from 3.2.2-9 to 3.2.2-x, but not from 3.0.x-x to 3.2.x-x.
To upgrade to the specific OnApp Control Panel version, perform the following steps:
Run the following command to eliminate all of the files which yum uses to determine the remote availability of packages:
bash# yum clean metadata
Remove OnApp:
bash# yum remove onapp-cp
Install OnApp Control Panel installer package for the required Control Panel version:
bash# yum install onapp-cp-<ONAPP_VERSION>
Where:
ONAPP_VERSION - the required OnApp version with its build, e.g.3.2.2-15
