>                 Key: STORM-3026
>                 URL: https://issues.apache.org/jira/browse/STORM-3026
>             Project: Apache Storm
>          Issue Type: New Feature
>          Components: storm-core
>    Affects Versions: 1.0.0, 2.0.0
>            Reporter: Robert Joseph Evans
>            Assignee: Robert Joseph Evans
>            Priority: Major
> It would be great to have the ability to move an existing cluster with it's 
> ZK from insecure to secure without wiping everything clean.  This does not 
> allow for a rolling upgrade because the running topologies will not have the 
> credentials that they need, but you don't need to do the manual step of 
> deleting the root ZK node.
