Index Alias Using NEST

Elastic Stack Elasticsearch
1

As usual No doc assistance when using NEST. We came across this OLD code on Stackoverflow:

>     createIndexResponse = client.CreateIndex(indices[1]);
> 
>     // wait for index-v2 to be operable
>     var clusterHealthResponse = client.ClusterHealth(c => c
>         .WaitForStatus(WaitForStatus.Yellow)
>         .Index(indices[1]));
> 
>     // swap the alias
>     var bulkAliasResponse = client.Alias(ba => ba
>         .Add(add => add.Alias(alias).Index(indices[1]))
>         .Remove(remove => remove.Alias(alias).Index("*"))
>     );
> 
>     // verify that the alias only exists on index-v2
>     var aliasResponse = client.GetAlias(a => a.Name(alias));

But we are confused:
1- There is no ClusterHealth anymore.
2- The code that first Adds and then removes alias from All indexes - will that not remove the alias as well from the new index?

Would appreciate any assistance.
