When the kubernetes ASG is manually managed, we manually stopping pods to draining nodes into nodes update.

We want to use self managed node groups, but planning the migration, we think that the migration nodes data, and resharding his data, have high chance to fail.

There're some reccomended acctions or procedure to control resharding data into Rolling update?

Thanks,

You can use the [cat shard API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-shards.html) (`/_cat/shards`) and the [cluster allocation explain API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-allocation-explain.html) (`/_cluster/allocation/explain?pretty`) to monitor Elasticsearch shards rebalancing.
