We are using ElasticSearch 2.x on AWS EC2 instance. This is the latest version they have available and we are not getting any response to if they will ever upgrade it to the latest version.
So we need to use curator on our job server to organise time-series data and drop older indices. My question is can we use the latest version of curator 4.2.4 with ElasticSearch 2.x ?
Or do we need to use some specific version?
