Hi Everyone,  
I am trying to upgrade Elasticsearch cluster version from 7.17.28 to 8.17.6.  
I could see one node was successfully upgraded from 7.17.28 to 8.17.6, and it was automatically removed from the 7.x cluster after 1–2 minutes without issue.

Please can anyone let me know if I could do rolling upgrade for each nodes one by one from 7.17.28 to 8.17.6? Do I need to stop all nodes and then upgrade all nodes, then start them one by one.

Thanks.

Yes a rolling upgrade from 7.17.28 to 8.17.6 will work.
