I have two elasticsearch cluster with verison 5.6.8.  
I want to copy index data across them, but as far as I know, cross-cluster-replication is enabled after 6.5.  
Is it possible to install ccr on an older version of elasticsearch?

No it is not. I would however recommend upgrading as Elasticsearch 5.x has been EOL for quite some time.

Just to reiterate that point - 5.X has been [EOL](https://www.elastic.co/support/eol) since 2019-03-11.  
Please upgrade.
