Hello,

I am upgrading the Elasticsearch instance from 7.5.1 to 8.4.3 but it's not working.  
I have created an Elasticsearch instance in Ubuntu 18.04 with version 7.5.1 and created a sample index and populated the data.  
After that, I upgraded the instance to 7.17.1 and it's working fine.  
But after that, if I upgrade to 8.4.3 it's not working.

Could you please provide step-by-step instructions to solve the issue?

Thanks and regards,  
Suraj jannu

Hi Suraj,

Are you using the upgrade assistant for 7.17.1 to 8.4.3 as per the [upgrade guide](https://www.elastic.co/guide/en/elastic-stack/8.4/upgrading-elastic-stack.html#prepare-to-upgrade)? The upgrade guides that list the appopriate steps for cloud and on-prem installations are here:

- [Cloud](https://www.elastic.co/guide/en/elastic-stack/8.4/upgrade-elastic-stack-for-elastic-cloud.html)
- [On-prem](https://www.elastic.co/guide/en/elastic-stack/8.4/upgrading-elastic-stack-on-prem.html)

If those steps are not quite working can you share any errors that you are getting, or details on what exactly isn't working?
