Hello all,

I copied the data from one elastic server to new elastic server facing the authentication issue .

```

I move your question to #x-pack.

Can you provide more details?

- How did you copy the data?
- Did you copy the `.security` index also?
- Is this error being caused by a Kibana server, or through manual testing?
- Is it only the _kibana_ user that is failing, or is _elastic_ failing as well?
- Was the old server using the default _changeme_ password, or had you changed it?
