How to migrate redis cluster without down time

We have two different running redis clusters and we want to migrate one to another. Both of them are serving and down time is not allowed.

Is there a recommended solution for the migration of redis?

You could consider using redis-shake which allows non-blocking incremental syncing.

You can easily configure it to sync from cluster-to-cluster, standalone-to-cluster, and so on.

Configure the source and target in the sync.toml:

Then run:

./bin/redis-shake sync.toml

You can basically just make one instance the slave of the other temporarily, and it will migrate all data for you. https://groups.google.com/forum/m/#!topic/redis-db/KOhA-TD1V6U

Or if you are wanting to just move some keys, the migrate/move command will allow you to move values per key, which you could iterate over to move many.
