Environment

• CB Response Server: 6.X

Objective

Re-apply upgrade configurations to Response Server
 

Resolution

Upgrade can be re-applied through the following:

1. Stop the Response Server/Cluster services: https://community.carbonblack.com/t5/Knowledge-Base/Cb-Response-How-to-restart-server-services/ta-p/...
2. Edit the /var/cb/data/SCHEMA_VERSION to point to previous Response build ID: 

   From: 6.3.0.190325.2042 
   To: 6.2.4.181112.1340

3. Save the changes to SCHEMA_VERSION
4. Run /usr/share/cb/cbupgrade
5. Start the Response services

Additional Notes

Example Scenario: 

• Previous version of Response Server migrated to new Server, but new Server is running latest version of Response.
• Due to migration of config files from previous version, latest version of Response may fail to start or login the user.
