So there is no down time, and the airflow traffic can be redirected to a higher EMR version using the new version of megastore. I have found a post : https://aws.amazon.com/blogs/big-data/upgrade-amazon-emr-hive-metastore-from-5-x-to-6-x/ , but it requires the megastore to stop for some time. Thanks. Have a great day!
