Upgrades to the Carbon Black EDR server occasionally require you to use a utility called
cbupgrade after executing
yum update cb-enterprise to migrate the database schema or Threat Intel feed data.
You are notified of this requirement when attempting to start the cb-enterprise services. In a clustered-server configuration, you must run the
cbupgrade tool on all nodes before restarting the cluster. When running this utility in a clustered environment, be sure to answer No when asked to start the Carbon Black EDR services. You must use
cbcluster to start the clustered server.
