Migration from OpenSearch2.5 to Elasticsearch8.8.1

Elastic Stack Elasticsearch

Hello.
I'm thinking of migrating from AWS OpenSearch to Elastic Cloud.
First, I launched Elasticsearch 8.8.1 locally with docker and checked if the data could be migrated.

Data migration experimented with Snapshot & Restore.

As a result, as shown below, the version of OpenSearch is too large and an error occurs if there is no compatibility.

the snapshot was created with Elasticsearch version [36.26.78] which is higher than the version of this node [8.8.1]

As far as I can see from the error message, is it impossible to migrate data with Snapshot & Restore?

  • from: OpenSearch 2.5
  • to: Elasticsearch 8.8.1(docker local)
  • storage: AWS S3

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.

You can't restore a snapshot created in OpenSearch on a Elasticsearch cluster.

If you want to migrate the data from Opensearch to Elasticsearch you will need to use something like Logstash for example that will query your Opensearch cluster and index the data in your Elasticsearch cluster.

Thank you for your response.
I understand that it is not possible to restore from OpenSearch.
I would like to explore the option of using Logstash or similar tools to migrate the data.

A remote reindex should work as well.

After experimenting with Docker, I successfully achieved the desired results with remote reindexing!
I will try it next using Elastic Cloud.

Thank you!

Hi ,

I was also trying to migrate data using remote re-indexing from AWS Opensearch 1.3 to ElasticCloud 7.17 but facing below error

{
        "type" : "status_exception",
        "reason" : "body={\"error\":{\"root_cause\":[{\"type\":\"illegal_argument_exception\",\"reason\":\"No search type for [scan]\"}],\"type\":\"illegal_argument_exception\",\"reason\":\"No search type for [scan]\"},\"status\":400}"
 }

I am new to Elasticsearch so not much idea what could be wrong.
Any suggestions here what could be wrong and how i can achieve migration?

Welcome!

Could you describe exactly what command you are running and where?
Could you also open a new topic on this problem as the previous one have been solved. :slight_smile:
