#### Fix for `multiple_es_nodes.test.ts`
Inspired on elastic#193899

1. Start both nodes of ES 8.17.0 with the affected data-archive on
separate terminals:
1. Node 01: `yarn es snapshot --version=8.17.0 --data-archive
src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_01.zip
--base-path .es/node01`
2. Node 02: `yarn es snapshot --version=8.17.0 --data-archive
src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_02.zip
--base-path .es/node02`

2. After ES is ready (without starting Kibana), reindex the index
`.kibana_7.13.0_002`
1. Retrieve the settings from the original index via `curl -L
'http://localhost:9200/.kibana_7.13.0_002' -H 'Content-Type:
application/json' -H 'kbn-xsrf: test' -H 'Authorization: Basic
c3lzdGVtX2luZGljZXNfc3VwZXJ1c2VyOmNoYW5nZW1l' -d ''`
	2. Create the target index with those settings: 
	```shell
curl -L -X PUT 'http://localhost:9200/.kibana_7.13.0_003' -H
'Content-Type: application/json' -H 'kbn-xsrf: test' -H 'Authorization:
Basic c3lzdGVtX2luZGljZXNfc3VwZXJ1c2VyOmNoYW5nZW1l' -d '{

                    "ignore_above": 256
                  }
                }

                }
              }
            }
          },
          "namespace": {

          },

          },
          "updated_at": {

            "number_of_replicas": "0"
        }
      }
    }'
         ```
3. Reindex the content: `curl -L 'http://localhost:9200/_reindex' -H
'Content-Type: application/json' -H 'kbn-xsrf: test' -H 'Authorization:
Basic c3lzdGVtX2luZGljZXNfc3VwZXJ1c2VyOmNoYW5nZW1l' -d '{ "source": {
"index": ".kibana_7.13.0_002" }, "dest": { "index": ".kibana_7.13.0_003"
} }'`
    4. Remove the old index and recreate the aliases
    ```shell
curl -L 'http://localhost:9200/_aliases' -H 'Content-Type:
application/json' -H 'kbn-xsrf: test' -H 'Authorization: Basic
c3lzdGVtX2luZGljZXNfc3VwZXJ1c2VyOmNoYW5nZW1l' -d '{
  "actions": [
{ "add": { "index": ".kibana_7.13.0_003", "alias": ".kibana_7.13.0_001"
} },
    { "remove_index": {"index": ".kibana_7.13.0_002" } },
{ "add": { "index": ".kibana_7.13.0_003", "alias": ".kibana_7.13.0" } },
    { "add": { "index": ".kibana_7.13.0_003", "alias": ".kibana" } }
  ]
}'
	```
3. Stop both ES nodes.
4. Compress both archives
	```shell
	cd .es/node01/8.17.0
rm -rf data/nodes # we need to remove this dir or it fails to start
again
zip -r
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_01.zip
data -x "*/\.*"
	cd ../../../
	cd .es/node02/8.17.0
rm -rf data/nodes # we need to remove this dir or it fails to start
again
zip -r
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_02.zip
data -x "*/\.*"
	cd ../../../
	```
5. Run the tests to confirm that the issue is fixed: `yarn
test:jest_integration
src/core/server/integration_tests/saved_objects/migrations/group3/multiple_es_nodes.test.ts`
