Hi, I am trying to copy the data from our old Elasticsearch 6.2.4 to the new elasticsearch 7.6.1 I tried the following methods. Snapshot and restore Re-index from a remote cluster. Both methods seem working but I got Yellow color health status in the new server. Also, what does yellow mean? and I got that status in old elastic server 6.2.4. What happened in the Elasticsearch 7.6.1 once the data is moved from Elasticsearch 6.2.4 - I see all the indices in the yellow color status. - In the new Elasticsearch authentication failed immediately. I attached the log in the bottom. When I searched about that solution are clean up the data and point to the new data directory in the elasticsearch. **My questions** 1. Basically, How to change the Yellow color health status to Green? 2. If I do the mappings manually in the new server and moved the data is that enough to get Green status? I am trying to figure this out If possible can someone help with this? Thanks Saravana ---

Welcome! What is the output of: ```auto GET / GET /_cat/nodes?v GET /_cat/health?v GET /_cat/indices?v ``` If some outputs are too big, please share them on [gist.github.com](http://gist.github.com) and link them here. ---

Please format your code, logs or configuration files using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button.

> [@TheOne](#): > > Elasticsearch 7.6.1 always show authentication error once I restore the data from the old server You probably need to fix this problem. Not sure how you saw them that the cluster is yellow. But anyway, in the old cluster it's yellow as well. So everything looks fine. It can't be green if you have at least one index with the number of replicas greater or equal to 1 and only one node in your cluster. ---

Ok, thanks. Elasticsearch 7.6.1 I enabled authentication and set up the password for elastic user. but after the restore process its throwing that error. I will try to fix that ========================================================== ] [node-1] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic] =========================================================== ---

You need to provide the credentials when your cluster is secured. ---
