Each new version of the Carbon Black EDR server might add or remove some parameters in the cb.conf file, or change the defaults for existing parameters.
When you install a new version of the server, the upgrade program does not overwrite the existing cb.conf file. Instead, it preserves any custom changes you have made to cb.conf and creates a new file called cb.conf.upgrade .
Examine the cb.conf.upgrade file as well as this document to determine what parameters are new or changed in the current release. You can then either copy the relevant new (or changed) sections from cb.conf.upgrade into cb.conf , or replace cb.conf with an edited version of the upgrade file.
