I have one node cluster of Elasticsearch  
With installed Elasticsearch, kibana, apm-server  
I have about 5 TB of indices

my elk version is

```auto
{
  "name" : "elk-old",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "qLR6jhtgS627KCq7Ls-dxQ",
  "version" : {
    "number" : "7.5.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "e9ccaed468e2fac2275a3761849cbee64b39519f",
    "build_date" : "2019-11-26T01:06:52.518245Z",
    "build_snapshot" : false,
    "lucene_version" : "8.3.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

```

Now I want to install 3 additional nodes with hardware characteristics different to the old-elk instance:

old-elk: 10 cpu, 64 ram, 10 tb disk  
new-nodes: 10 cpu, 64 ram, 5 tb disk for each one

My goal is to add three additional nodes to the cluster and store all new indices on them  
old indices should be available for reading and store on old node  
old indices will be automatically deleted after 1 month  
and after 1 month I have to exclude old node from the cluster and shutdown it

How can I achieve this right way?
