We have a single Redis instance with a good amount of data (over 100GB). We also have an empty Redis Cluster with 6 nodes. What would be the best way to move all that data from the stand-alone instance to the Redis Cluster and make it distribute it evenly?
After some searching around, I came across a post detailing how to move data over to a cluster. It may take some time to move lots of data over but this is the best way I've seen so far.
