Upgrading Control Center

Upgrading from version 3.0.0

NOTE: the upgrade process will delete historical stream monitoring data older than the configured retention time (confluent.monitoring.interceptor.topic.retention.ms) for the stream monitoring topic.

1. Stop the Control Center process

2. Copy the 3.0.0 configuration file

   $ sudo cp /etc/confluent-control-center/control-center.properties /etc/confluent-control-center/control-center-3.0.0.properties
   

3. Upgrade to version 3.0.1

   $ # Via yum
   $ sudo yum update confluent-control-center
   $ # Via apt-get
   $ sudo apt-get update && apt-get upgrade confluent-control-center
   

4. Reset the application (deleting internal state)

   $ # Use the same properties file you used to launch Control Center
   $ /usr/bin/control-center-3_0_0-reset /etc/confluent-control-center/control-center-3.0.0.properties
   

5. Edit the Control Center properties file. Some configuration property names have changed

   • Change confluent.controlcenter.id from 0 to 1. This isn’t strictly necessary but a good precaution in case any step of the reset failed.

6. Start Control Center

   $ /usr/bin/control-center-start /etc/confluent-control-center/control-center.properties
