Upgrade ChaosCenter

To upgrade Litmus ChaosCenter from 2.0.0-Beta9 to 2.0.0, you can follow these steps:

  1. Disconnect the agent components To disconnect agents, you can do it from the chaoscenter by clicking the disconnect button. With this, the subscriber deployment and agent-config will be removed from the agent cluster.

    kubectl apply -f https://raw.githubusercontent.com/litmuschaos/litmus/2.0.0/docs/2.0.0/litmus-2.0.0.yaml

  3. Reinstall the agent components using litmusctl

    Note: While reinstallation, make sure to use the same agent name

    To reinstall the ChaosAgents, use Litmusctl

Upgrade Mongodb DB Schema
