Hi All,
While performing migration of kibana using eck-operator from 7.8.1 to 7.17.10, we are facing the following issue:
```auto

```
This is leading to kibana health status as red. On deleting the .kibana index, kibana health is back to green but I am not sure if deleting is the appropriate approach. Could you please suggest, if there are any strategies to resolve the same.
