I currently have a 1.2.0 environment of poensearch and dashboards.
I need to update my environment to 2.3.0.
My environment is clustered with docker.
I simply tried to replace the opensearch docker image from 1.2.0 to 2.3.0 and it lost the indices that were stored, despite appearing when I gave the command “GET _cat/nodes”.
It seems to me that it was something related to the change in Lucene’s version.
How should I upgrade my environment from 1.3.0 to 2.3.0.
There are 4 servers with opensearch, 1 master, 1 coordinator and 2 data. And 1 from opensearch dashboards.
OpenSearch 1.2 is on Lucene 8.x and 2.3 is on 9.x. Lucene should read one major version behind, so I doubt it’s a Lucene issue. Or if it is, it should show up in the logs.
Speaking of logs, does anything show up there? Any error of loading something?
Or maybe the data was stored in the container instead of volumes?
