How to upgrade elastic search from 1.7.x to 7.0?

I am in need of a solution to upgrade/migrate elasticsearch from 1.7.6 to 7.0 with all the data and the reports. Is there any way to do it?

Thanks in advance.

You have to install elastic search 7.0 and reindex the data again.

You can't just migrate the old indexes of elastic search 1.7 to elastic search 7.0.

Elasticsearch can read indices created in the previous major version. If you have indices created in 5.x or before, you must reindex or delete them before upgrading to 7.1.1. Elasticsearch nodes will fail to start if incompatible indices are present. Snapshots of 5.x or earlier indices cannot be restored to a 7.x cluster even if they were created by a 6.x cluster.

Refer elastic search documentation
