So, I'm currently testing some edge cases within cross cluster replication and upgrading elasticsearch.
The thing is, when you upgrade an elasticsearch cluster (bi-directional setup), you have to pause following on all indices which follow something (see https://www.elastic.co/guide/en/elastic-stack-overview/current/ccr-upgrading.html#_bi_directional_index_following)
The issue we stumbled on is, that the auto-follow pattern is still in place and will start replicating when a new index is created at the leader cluster, which we would have to stop following instantly again to properly upgrade the cluster.
So my question in the end is, is there a way to pause and disable autofollowing for the whole cluster while in an upgrade scenario?
Thanks in advance
