CoreMedia Digital Experience Platform 8 Developer Manual, Version 7.5.45-10
4.2.3. Upgrade a System | 4.2.3.2. Upgrade with Yum

The first step, you should do, when you want to update your system, is to find out what package updates are available. With YUM, you simply call yum list updates cm8-*

In a second step, you may check if your configuration files below /etc/coremedia are still up to date or if there are any changes required. You can do that manually by inspecting the package description for each update or you can update the packages and see if there are missing tokens. By default, the CoreMedia RPM files will check if all necessary properties are defined in the configuration file, if that already exists. If properties are missing, the package won't be installed and the missing properties will be reported on the console or in the system log at /var/log/messages.

To print out the description of an RPM, you need to execute:

yum info <PACKAGE NAME>

If for example, you execute yum info cm8-wfs-tomcat the RPM metadata will be printed and in the description, you will see a list of properties you need to define.
