I am getting 'occasional' 500 Transport errors on AWS managed ES stack when posting JSONS from our python based lambdas. This was working flawlessly until today's upgrade to ES 7.9. We have tried increasing the cluster sizes as per the AWS best practices. The error goes away for a while and pops up…

Reindex from remote does that for you.

Getting TransportError: TransportError(500, 'exception', 'java.io.OptionalDataException' while posting to AWS managed elastic stack

Thanks for the idea.
I was reading its documentation. Is it possible to perform reindex from remote with source as a 7.9 cluster and destination as a cluster v7.7?
