Hi there,
We are trying to upgrade elasticsearch stack from 7.4.0 to 7.10.2, however when upgrading to 7.10.2 we are facing the following error message from kibana logs.
```auto
{"type":"log","@timestamp":"2021-05-03T13:20:35Z","tags":["warning","plugins","licensing"],"pid":1,"message":"License information could not be obtained from Elasticsearch due to [illegal_argument_exception] request [/_xpack] contains unrecognized parameter: [accept_enterprise] :: {\"path\":\"/_xpack?accept_enterprise=true\",\"statusCode\":400,\"response\":\"{\\\"error\\\":{\\\"root_cause\\\":[{\\\"type\\\":\\\"illegal_argument_exception\\\",\\\"reason\\\":\\\"request [/_xpack] contains unrecognized parameter: [accept_enterprise]\\\"}],\\\"type\\\":\\\"illegal_argument_exception\\\",\\\"reason\\\":\\\"request [/_xpack] contains unrecognized parameter: [accept_enterprise]\\\"},\\\"status\\\":400}\"} error"}
```
Even a rolling upgrade from 7.10.1 to 7.10.2 does not seem to fix/bypass this issue, it only shows on 7.10.2.
The license we have is a platinum tier.
Can anyone provide some guidelines as to what would be the best approach to fix this?
If you require any more info I will attach whatever is needed.
Thanks

Hi @IBoskov Welcome to the community.
Sorry you are having issues.
Since your are a platinum customer I highly recommend open a support case, they should be able to help you and are experts on these kind of issues.

It sounds like you might still have a 7.4 node in your cluster.
Can you double check?
```auto
GET /_cat/nodes?v=true&h=id,ip,port,v
```

Hi @TimV all nodes are upgraded to 7.10.2, and as I mentioned this only happens when upgrading to 7.10.2.
Previously the upgrade was on 7.10.1 and there was no issue related with the license, I wouldn't expect to have much changes between two sequential minor versions.
```auto
id port v
3Tiy 9300 7.10.2
RBWw 9300 7.10.2
cMCp 9300 7.10.2
8qsr 9300 7.10.2
wO1f 9300 7.10.2
ITK8 9300 7.10.2
uv3I 9300 7.10.2
tU28 9300 7.10.2
```
