hello  
i have created cluster of 2 nodes  
node1: master node  
node2: data node

the cluster state is red because the old index existing before creating my cluster are in red state.

i would like to know if i can turn my old index to green state and not lose them.

thanks in advance for your replay

Could you run [cluster allocation explain api](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/cluster-allocation-explain.html) for this index to see why it's red?
