Can't upgrade elasticsearch 5.2.1 to 5.6.5

Elastic Stack Elasticsearch
14

Maybe the problem is related to the template settings.
Because not all nodes have the settings:

node.attr.zone: zone_one
node.attr.disk: ssd
Or 
node.attr.zone: zone_one
node.attr.disk: sata

,i select the include and exlude settings for index:
the template:

default:
{
  "order": 0,
  "template": "*",
  "settings": {
    "index": {
      "routing": {
        "allocation": {
          "exclude": {
            "disk": "sata"
          }
        }
      }...
other tempate:
{
  "order": 1,
  "template": "apm.store_tranport-*",
  "settings": {
    "index": {
      "routing": {
        "allocation": {
          "include": {
            "disk": "sata"
          },
          "exclude": {
            "disk": null
          }
        }
      }
...

I think i can add the node.attr.disk: ssd settings for the nodes needed, then restart the nodes, modify exlude to include which maybe solve the issue.
