Hello, I would like to migrate away from a manually installed OpenSearch instance to Graylog-Data on a RHEL 9.X host.
Opensearch had been updated to 2.19 as we weren’t aware that we needed to place a version lock on it, so we’re looking at how to migrate from it to Graylog-Data.
Some downtime is fine as this server isn’t in full production, but we’d rather not rebuild it and lose all historical data if possible.
