We are having 2 separate clusters in 2 different data centers and currently they are active-active.
After Elastic 6.0, synchronization will be in place.
So if data ingestion is enabled for one Elastic Cluster/Data Center with syncing to the other Data Center (from A to B) is enabled, Can I run from one Data Center and stop maintaining two distinct-parallel Clusters? At the time of the switch over, the sync process will be enabled from B to A. (making sure first A to B sync first is completed)
is this the right approach? Does anyone tried this and what were the caveats?
