**Versions**  
OpenSearch = 1.3.6  
Operating System = Debian

**Describe the issue** :  
I wanted to know which version of Elasticsearch can be migrated to Open search 1.3.6, we are using Graylog with Elasticsearch 7.16 and we wanted to move to OS from ES.

from Graylog documents it says that anything beyond ES7.10 wont be migrating to Opensearch version of 1.X

I wanted to know re-indexing from ES7.16 to OS 1.3.6 will work or not. or it will give some issues.

Please guide us,

Regards,  
SAM

Look for my post [here](https://community.graylog.org/t/elasticsearch-7-17-8-with-error-update/27274/2).  
In general migrating from versions above 7.10 is very painful.
