Hi,

You will be interested by this article explaining a Redis migration very similar to yours: between an old and new cluster.

See https://medium.com/afilmycode/how-we-migrated-aws-elasticache-redis-cluster-to-another-in-production-e67e8af33dab

They even provide the Python code to do tis migration and check for the absence of discrepancies.

Best,

Didier
