I have the ES cluster with 9 shards and replicas, where all the data is
stored locally on the nodes. We have the process complete data migration
from one system to another. Since introduction of ES - we need to be able
to migrate also ES indices. We are using Netapp snap-mirror mechanism for
the rest of the data.
What would be the best practice, so, when the second system starts it will
actually build the cluster from migrated data.
