Hi, everyone.
I'm trying to upgrade ES from 5.4.0 to 6.8.0.
According to official documents, I execute this method after upgrade:
curl -XPUT -H "Content-Type:application/json" 172.16.1.133:9200/\_cluster/settings -d'
{
"persistent": {
"cluster.routing.allocation.enable": null
}
}
'
And I got error:
{"error":{"root\_cause":[{"type":"illegal\_argument\_exception","reason":"unknown setting [archived.xpack.security.transport.filter.deny] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"}],"type":"illegal\_argument\_exception","reason":"unknown setting [archived.xpack.security.transport.filter.deny] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"},"status":400}
How can I solve this problem?
Thanks and regards!

Somewhere along the way, Elasticsearch has failed to recognise your `xpack.security.transport.filter.deny` setting and has archived it. You must remove any archived settings before you can set any other settings. I think this is a valid setting, as long as you are not using an unusual distribution. Can you share the output of `curl http://172.16.1.133:9200/`?
To remove an archived setting, set it to `null`:
```auto
curl -XPUT -H "Content-Type:application/json" http://172.16.1.133:9200/_cluster/settings -d'
{
"persistent": {
"archived.xpack.security.transport.filter.deny": null
}
}'
```
