Environment
- Carbon Black EDR: All Versions
- RHEL/CentOS: All Supported Versions

- When upgrading from a new major version the product needs to be uninstalled prior to performing the upgrade and re-installed. ex. 7.6 to 8.9
- Stop the EDR services.

cluster:
/usr/share/cb/cbcluster stop
- Uninstall the EDR Application prior to performing the in-place upgrade.
yum remove $(yum list installed | grep CarbonBlack | awk '{ print $1 }')
- Perform in the in-place OS upgrade. Documentation can be found from OS support on how to perform these steps.
- Reboot the server if this has not been done already.
- Re-install the EDR application.
yum install cb-enterprise
- Start the services.
standalone:
/usr/share/cb/cbservice cb-enterprise start
cluster:

Additional Information
- Failure to uninstall the product prior can lead to errors in the in-place upgrade when it detects the old EL version packages existing on the machine
- EDR services will fail to start if the in-place upgrade is performed successfully and old packages still exist.
- Uninstalling the EDR only uninstalls the application, all configs and data will remain.
- 3rd party libraries and dependency packages are different between major versions.
