Changing Policies

You can change any managed index policy. ISM has constraints to ensure that policy changes do not break indices.

If an index is stuck in its current status, never proceeding, and you want to update its policy immediately, make sure that the new policy includes the same status (same name, action, and order) as the old policy. In this case, ISM applies the new policy even if the policy is being executed.

If you update the policy without including an identical status, ISM updates the policy only after all actions in the current status finish executing. Alternatively, you can select a specific status in the old policy and have the new policy take effect.

To change a policy using Kibana, do the following:

1. Under Managed Indices, select the indices to which you want to attach the new policy.
2. Click Change policy in the upper right corner. The Choose managed indices page is displayed. Configure parameters required for changing a policy.
