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 again after couple of hours. We are sending about 220 POST request to the ES service every 15 mins. **Python stacktrace** ``` [WARNING] 2020-12-04T15:27:27.558Z c4bad482-15ba-4a59-ac00-018a3dc893a4 POST

success rate consistently when this error occurs. Lambda retires seems to take care of the failed requests, by retrying when anything fails & it goes through that time. So its isn't data related. Could some one please explain what could be going on? ---

AWS support got back to us. they said its an issue with 7.9 and asked to downgrade to 7.7 by taking a manual snapshot. So much for being a managed service. I will update here if that solves the issue ---

Aws support said its possible by : [https://aws.amazon.com/elasticsearch-service/faqs/](https://aws.amazon.com/elasticsearch-service/faqs/) " Q: Can I downgrade to previous version if Iā€™m not comfortable with the new version? No. If you need to downgrade to an older version, you must take a snapshot of your upgraded domain and restore it to a domain that uses the older Elasticsearch version." Update : I am not just quoting docs, their support person told us that its possible. ---

A snapshot created in a newer version can not be read by older versions, so that sounds wrong. ---

Thanks for the heads-up!! What we ended up doing was extracting all the \_ids using the scroll API for all objects from old cluster AES 7.9. (elasticsearch\_dsl python library) Then extract the actual '\_source' json using an mget query on the old cluster using those ids and used that json to push to our new cluster which has AES 7.7. ( using elasticsearch python library) I am sure there is an easier way to do this, but this what we could script very quickly. ---

@dadoonet thank you for idea on remote from reindex. It was blazingly fast, given Elastic was designed to handle billions on documents. Pro tip to anyone else performing remote reindex temporarily set replicas to zero for the destination, to speed up things. ---
