I am trying to migrate data from Cluster 1(Elasticsearch version-6.4) to Cluster-2(Elasticsearch version-7.12). Have taken the snapshot and trying to restore the snapshot and seeing the error shown in the attached image.
My old clusterElasticsearch version-6 has 5 shards by default and the new cluster with Elasticsearch version-7 has 1 shard by default.
Do I need to make my cluster to use 5 shards similar to my old cluster? If so where can I update that? Any help/suggestions appreciated.
