To upgrade Kafka from version 1.1.0 to 1.1.2, a manual update is required. For all other versions, the update process is automated.
Warning: The update will delete the agent's volume
and erase data from existing topics. New topics will be created after installation.
Be sure to back up important data beforehand to avoid data loss.
Prerequisite: Before proceeding with updates, ensure that the workload is stopped. This suspension is necessary to prevent data inconsistency and ensure a smooth maintenance process.
Steps to follow for updating the Kafka version:
- Before updating kafka version, ensure to update the data integration services.
- Update the CLI by executing this command
./discli updateCli - Stop agent by running this command
./discli agent stop - Apply kafka version by executing this command
./discli agent applyKafkaVersion 1.1.2 - Start the agent by running the command
./discli agent start - Ensure that the agent is healthy, operational, and running as expected.
- Once the agent is confirmed to be healthy, start all the workloads.
