Migrate AWS ElasticSearch data from one domain to Another - Different versions

Hi Everyone,

I need to migrate AWS ElasticSearch data from one domain to another within same account, but both the domains have different versions of Elasticsearch i.e. migrate from 6.3 in one domain to 7.4 in another domain.

Please suggest the most feasible method with Index Mapping impacts, if any.

Thanks,
Mehak

You could may be use reindex from remote for this?

BTW did you look at https://www.elastic.co/cloud and https://aws.amazon.com/marketplace/pp/B01N6YCISK ?

Cloud by elastic is one way to have access to all features, all managed by us. Think about what is there yet like Security, Monitoring, Reporting, SQL, Canvas, APM, Logs UI, Infra UI, SIEM, Maps UI, AppSearch and what is coming next :slight_smile: ...

Thanks for your reply, @dadoonet.

I was wondering if that would work, since the the documentation says that ElasticSearch version should remain the same (https://www.elastic.co/guide/en/cloud/current/ec-migrate-data.html#ec_before_you_begin_4)

It says;

The new cluster must be the same size as your old one, or larger, to accommodate the data.

@warkolm,
That is when I would need to index from the source itself, and that would require availability of original source. Please correct me if I'm wrong, since I am new to ElasticSearch.
Also, I have new data in my ES 7.4 domain, and I would require data of the 7.4 as well as the migrated data from ES 6.3's domain.

That is correct.

I think you may need to ask AWS support about the domain aspect, that's outside out scope of understanding here sorry.

@warkolm,
Not a problem, thanks for your inputs.
