Hi, This is Jason.

I would like to add remote cluster which is free-tier 6.0 with our platinum-tier 6.8 cluster.

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/a/6/a66bb00d5e11c4c917368fa1903a83db329083e1.png)

But I have no success to add this remote cluster.  
I confirmed firewall is open so I can get remote cluster's health via REST API.

AFAIK, 6.0 and 6.8 is transport compatible.  
[reference : [https://www.elastic.co/guide/en/elasticsearch/reference/6.8/modules-remote-clusters.html#remote-cluster-settings](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/modules-remote-clusters.html#remote-cluster-settings)]

In addition, Can I create a ML-job with indices on remote cluster?

Thanks & regards,  
Jason.

are there any messages in the elasticsearch logfiles that could help identifying the problem, that you can share in a gist?

Sorry for the late.

Here are my logs

As far as I know you can not have a cluster with ML enabled run jobs against data in clusters without the appropriate commercial license.

Thank you, Christain.

I thought It is possible to create a ML job on ML cluster with datafeed via CCS.  
I'd better create additional index for ML cluster.
